What does this mean?

I tried with vdr-1.3.3. It hangs without LD_ASSUME_KERNEL=2.4.

NPTL is more Posix conforming than linuxthreads, so there may be
differences in the *behaviour* of some pthread_* functions,
and especially in the interaction of threads and signals.

But I haven't had time to look into NPTL yet, so I don't
know what exactly could be the problem. But the SIGIO stuff
in vdr/thread.c could be the culprit...

Johannes
