Hi,
Would it be possible to use os.pipe() on all OSes except AIX?
Pipes and socket pairs may have minor differences, but some
applications may rely on these minor differences. For example, is the
buffer
For the record, pipe I/O seems a little faster than socket I/O under Linux
In and old (2006) email on LKML (Linux kernel), I read:
as far as I know pipe() is now much faster than socketpair(), because pipe()
uses the zero-copy mechanism.

On Linux, splice() can

constants: PIPE_MAX_SIZE (4 MB) and
