Default Unix pool size (1000) is insane and dangerous

[apsheronets]

I mean this one:

lwt/src/unix/lwt_unix_stubs.c

Line 934 in 3d6f0fa

static int pool_size = 1000;

Few years ago I made a simple image caching proxy server using cohttp (and lwt). The server was pretty loaded, and worked on an array of pretty slow (rotational) HDD's. This caused an unexpected problem: a proxy server process ate all of the available RAM (like 32GB) in a couple of days.

The fix was: let () = Lwt_unix.set_pool_size 30

I see nobody touched the default number in a decade. How about lowering it down like 20 times?
