Memprof-limits — Memory limits, allocation limits, and thread cancellation for OCaml

Memprof-limits is an implementation of (per-thread) global memory limits, (per-thread) allocation limits, and cancellation of CPU-bound threads, for OCaml. Memprof-limits interrupts a computation by raising an exception asynchronously and offers features to recover from them such as interrupt-safe resources.

The implementation uses OCaml's Memprof engine with a low sampling rate that does not affect performance.

An explanation of what must be done to ensure one recovers from a memprof-limits interrupt is provided. It summarises the experience acquired in OCaml in the Coq proof assistant, as well as in other situations in many other programming languages. To my knowledge, this has never been told in textbooks, so I thought it might be of general interest to the community.
