BTW, I'm not sure what tolerance OCaml has for allocation failures at lower 
levels, but you might consider using M_NOWAIT instead of M_WAITOK and simply 
returning a failure when memory is exhausted. This doesn't necessarily help you 
-- if you are out of memory, not a lot of work can be done in the system, but 
at least you could print a message, panic(), or similar, giving an easier to 
identify failure mode.
