GC callbacks #6675
Original bug ID: 6675
When writing performance sensitive programs, one spends a lot of time worrying about the time spent in the GC. However there are very few tools available to directly measure the time spent in the GC.
Can we have the OCaml runtime fire a C callback when:
It would be nice to have an interface where the user can supply C functions pointers for these situations. I imagine there will be constraints on the C callbacks -- for example, the callbacks must not modify or allocate OCaml memory.
