Are you sure that the new libthr was installed ? Compile and run the
following test, please, and show me the results. On the patched libthr,
the program must not output anything and exits with error code 0.
Sorry for not noticing and coming in late, but I think the
original change is wrong. I don't see in the 2013 POSIX spec
or Solaris 11 man page (haven't checked Linux yet) where
pthread_mutex_trylock() returns EDEADLK under any
circumstance.
