So it certainly appears that Solaris is out of conformance.
Some additional read()/write()/lseek() locking is needed

Does it mean that appending (O_APPEND mode) one file by multiple processes may work incorrectly?


I would appreciate it if some people out there would run this test
on other systems (Red Hat Linux, NETBSD, Apple OS X, HP-UX, IRIX)
and post the results.


I tried to run the test on the following systems:

2.6.32-27-generic-pae #49-Ubuntu SMP
2.6.18-194.el5 #1 SMP    (Red Hat)
2.6.16.60-0.21-smp #1 SMP    (SUSE)

It failed on all of them.


Thanks,
Dmitry
