A new feature thanks to the fine folks at Switchvox!

Browse Source 
If a deadlock is detected, then the typical lock information will be
printed along with a backtrace of the stack for the offending threads.
Use of this requires compiling with DETECT_DEADLOCKS and having glibc
installed.

Furthermore, issuing the "core show locks" CLI command will print the
normal lock information as well as a backtraces for each lock. This
requires that DEBUG_THREADS is enabled and that glibc is installed.

All the backtrace features may be disabled by running the configure
script with --without-execinfo as an argument
