What I find funny is that one of opponents of PHP threads earlier

I think I was the one to mention the latter, but as I started out
saying, and as others have said too, it's about the right tool for
the right job.  When choosing a tool, there are a number of factors
to consider - developer productivity, available skills, future
maintenance, performance, scalability, portability, parallelism,
performance etcetera.

Funny you should mention all that.  Let's say that you're longer
with that company, either by direct employment or contract
consultant. You've implemented C because you need 'thread'.  Now
your replacement comes in and has no clue about C even though your
replacement is a PHP guru.  How much headache is maintenance gonna
be?  Scalability? Portability? wow....
Who was the idi... who hired someone who wasn't suited for the job?
Tommy, that's a moot argument.  You can't fit a square peg in a round

Suited for the job?  You mean introduce more complexity to a problem
that what could be avoided to begin with if PHP has thread support?
Tommy, it's perfectly simple:  in my company we hire people with C
skills for C programming jobs. We hire people with database skills to
be database administrators.  We hire people with Linux skills to work
on Linux systems.  We explicitly do _not_ hire PHP web-programmers to
maintain our C code.  And vice versa for that matter.  No problem, no

That may just work out fine if you work directly for the company with
all the proper staffing.  But some of us work as consultants or for
companies without the proper staffing.  As such, let's dissect what
you mentioned:

1) PHP with internal thread support
2) PHP with external C/C++ thread support

* Performance - having external thread support, now you have to call
an extension (more memory usage and CPU cycles).  If you happen to
have a C/C++ guru who can then code that thread support into PHP
extension, wouldn't it still perform better at the core vs as an
extension because it's not talking to a 'middle man'?  Having said
that, not everyone has access to a C/C++ guru.  Thus not mass

Are you suggesting that you need to be a guru in C to write threaded C code? I think the word you're looking for is competent.

* Portability - if you're currently running PHP on Windows, but manage
to convince management to switch to *BSD/Linux, then you'd have to
rewrite that external thread support.  But for us consultants, we may
have 1 project the runs on Windows, the next may be *BSD/Linux.  PHP
code snippets goes a lot further versus your custom work around.
* Managability - should your need to upgrade PHP for either bug fix,
new features you'd want to implement to add more functionality to your
site, will that then break your custom external solution?  How much
more manageable is it if it's done under 1 language versus 2+?

Are you suggesting cross platform thread libraries don't exist? I wonder how Apache does it... or MySQL... or any number of open source cross-platform systems. If they implement their own, then by the virtue of the source being open, you can feel free to incorporate.
