[uml-user] Advice to all glibc 2.12 users

[Richard W. <ri...@no...>]

glibc 2.12's pthread_cond_signal() is broken on UML because it does not
have FUTEX_WAKE_OP.

The issue got fixed in 2.12.2:
http://sourceware.org/ml/libc-alpha/2010-08/msg00019.html

Sadly, some distros (like CentOS 6.0) still ship glibc 2.12.1.
So you have to expect problems when them on top of UML...

Thanks,
