Synopsis: [sysvipc] unexpected and unreliable behaviour when using SYSV semaphore, fork and pipe

State-Changed-From-To: open->closed
State-Changed-By: jilles
State-Changed-When: Sun Apr 25 11:26:12 UTC 2010
State-Changed-Why: 
The problem is that with libc_r SysV semaphores will block the entire
process. We are sorry that this will not be fixed in libc_r, but the
newer threading libraries do not have this problem.
