The Boehm collector just needs a signal to use for its own purposes.
"SIGRTMIN" is just a random signal chosen in the hope that it won't
interfere with the application's use of signals.  If SIGRTMIN isn't
defined on MacOS X, just pick some other signal to use; preferably
the one that is least likely to be used by the application.
