If I recall correctly, there was an Lwn.net article reporting a lkml
(the Linux kernel mailing list) discussion on that subject. One of
the proposals was for the kernel to send processes a signal (SIGFREE?)
requesting they free up memory (by running a major GC, for example)
whenever memory was running low. In theory this could in some cases
avoid the invocation of the draconian OOM killer.
Question: just how effective such a feature would be in the Ocaml case?
Best regards,
Dario Teixeira
