:hi folks,
:
:I tried some regression tests from freebsd and
:src/tools/regression/pipe/pipe-reverse.c[1] failed
:
:% ./pipe-reverse
:Wrote 32768 bytes, sleeping
:Wrote another 8192 bytes, 40960 total, done
:Read 16384 bytes, going back to sleep
:Read 8192 bytes, done
:FAILURE
:
:maybe you want to take a look at it

:http://www.freebsd.org/cgi/cvsweb.cgi/src/tools/regression/pipe/pipe-reverse.c
The test program is broken. read() calls to a pipe are not guarenteed
to return the number of bytes requested in the read() system call. They
can return fewer, and they do in this case.
