Normally, the garbage collector black-holes closures which are being
evaluated, as a space-saving measure. This option turns off
blackholing. You shouldn't ever need to use it.
Historical note: this option used to be used to work around a problem
with signal handling, where a signal handler might need to evaluate
blackholed closures. Signal handlers are now run in a separate
thread, and don't suffer from this problem.
