problems with sigtimedwait() after migrating from Debian to Red Hat

Hi,

With real-time signals I need to assign a process ID of the thread to
be woken up. On the Debian system I have a PID for each thread to
getpid() delivers me what I want. However, on the Red Hat ES4 system,
I have only one PID for all threads. getpid() returns the PID of the
main() thread an that I can not use because I hav to block SIGRT for
this thread.

How can I get sigtimedwait() to work in a specific thread?
