If any remote consoles are active at shutdown, any attempts to shutdown or restart (whether from the foreground or a remote console) will cause a segfault during module unload. No segfault when replicated with valgrind.
This is likely more serious memory corruption since there appears to be stack corruption in the backtrace, no further details are available:
Other threads appear to be all right, which is a strong hint this is corruption caused when trying to unload mod_sysop. Possibly related to recent changes to try to move away from pthread_cancel in that module and some others?

Remote consoles are still created using detached
threads, but are now cleaned up more properly.
Consequently, the concept of "killable" threads,
which was a kludge from the beginning, is now
removed, since nothing else uses it.
Closes#12
