Yes, it is occassionally used by Bacula to "brutally" wake up another thread
-- usually in timers with the purpose of making that thread exit.
By the way, what is important for the LD_ASSUME... is what kernel you are
running. It should *only* be used with 2.4 kernels, where it should be
harmless in all cases. It comes into play only when /lib/tls has been back
ported from 2.6 kernels to 2.4 kernels. This back port was done by RedHat,
and it was not totally compatible with pthreads. I believe that I *finally*
found the incompatibility and worked around it so that the LD_ASSUME may not
be needed even on 2.4 kernels with back ported /lib/tls support.
In any case, LD_ASSUME... should not be used with current 2.6 kernels. In
fact, if I am not mistaken, FC5 has removed support for old pthreads so who
knows what kinds of problems one will have.
The code in the Bacula scripts explicitly tests for 2.4 kernels before setting
LD_ASSUME...
