I've done that now (in thread.h for the moment) and have uploaded a modified
patch to

  ftp://ftp.cadsoft.de/pub/etc/vdr/mutex.diff

in which I have generally made the mutexes recursive.
Unfortunately, after a few channel switchings, there appears to be
a deadlock of some kind and I need to "kill -9" VDR...
Did I do something wrong?
