This won't be an issue with the skas4 patch, which uses a system call to
get new address spaces.

Before you go wild with locking, look at the callers and see if they are
re-entrant. This obviously won't work for things that are called from all
over the place, but if something is called from one place that is itself
locked, then you don't need to worry about it.
