as of (at least
AIX 5.3).
aix.c was required long ago because AIX did not offer the popular
dlopen(), dlsym(), dlclose(), and dlerror() functions - you had to
write them yourself.

If a user wants to specify a variable in terms of bits, he would have
to spell out the units completely, as in 4 gigabits, 20 kilobits,

Time units is easy:
1h = 60min = 3600s = 360ms
We don't need anything larger than seconds at the moment.

How about the obvious DTRACE( ) or some similar variant?

1) I think the most straightforward way to load an instrumentation

debugger client to a target server and to set global breakpoints.

WaitForMultipleObjectsEx() returns. That disassociates the socket from the Event (it will get re-associated the next time pgwin32_waitforsingleselect() is called.

Obviously you're now writing 12 extra bytes of overhead to each AllocChunkData (__FILE__, __LINE__, and callCount) and 4 bytes to each AllocSetContext (callCount).

that I think about it, SMB locking is very unreliable so Win32 would be an issue too.

that the postmaster is still running? At first blush, that seems more reliable than checking for a (possibly recycled) process ID.

We already have two platforms that don't use the SysV semaphore

all support SEM_UNDO.
Which platforms, just out of curiousity? I assume that Win32 is one of them.
