I cannot reproduce this myself.
If you have analyzed this, can you please put in details?
nptl/sysdeps/pthread/timer_*.c needs the mutex to guard the global variables
the pure userland implementation uses (see the vars in timer_routines.c),
but there is no such things when using kernel timers, the state is kept in
the kernel, so there is no need for the mutex.
When you talk about "a block of memory", can you please be a little bit more
specific on which exact block of memory it is (allocated by which function, used
for what) and which function accesses it after it is freed?
Which critical section are you talking about?
