event queue with thread for c++

[Han-Wen Nienhuys]

Hey Dan,

I thought you might know this.

To do https://codereview.appspot.com/561390043/ properly, I have to expand
the heap when GC notifies us that a collection took place. Unfortunately,
libgc notifications are done with the garbage collector lock held. So I'll
need schedule a call to GC_expand_heap on a different thread.

Would you know what is the best way to do this in C++ nowadays?

thanks,
