Gaaah, debugging showed me that what happens is that hooks for
pthread_mutex_unlock() from libX11 take precedence over those from

Why does libpthread.so provide weak symbols for those?!

On the other hand, the current pthread_mutex_lock() implementation poses
problem: it always inlines the fast path (an xchg instruction), so that libX11
hooks just _can't_ work.
