Matthew Parkinson ccc03ce0fc Protection against fork (#735) ...

If a thread forks, while another thread is holding an snmalloc lock, then the allocator could stop working.

This patch attempts to protect against the cases of this. There is one case that is not covered. If a fork occurs during the very first allocation. This can result in the installation of the fork handler racing with the fork, and all bets are off.
