Hi all,

I ran a test case for timer_getoverrun in posixtestsuite project based =
on kernel 2.6.1 with libc-2004-02-01. The case didn't return the =
expected overrun numbers as expected.=20

Platform:
--------------------
libc: 2004-02-01
Linux kernel: 2.6.1-mm2 SMP on ia32
gcc-3.3.3-20040209
Redhat EL-3.0-update1

Test Case and Output
----------------------
The case can be found at =
http://cvs.sourceforge.net/viewcvs.py/posixtest/posixtestsuite/conformanc=
e/interfaces/timer_getoverrun/2-2.c
Output: FAIL:  62 overruns sent; expected 75

I know there maybe some problems to let nanosleep sleep for the time =
equal to the time of the expired times. But is there any way to make =
sure the timer expire the accurate times we want? So then we can get the =
correct overrun numbers?=20

Attached the strace log.=20

Thanks,
Crystal
