Module Gc.Tweak

GC Tweaks are unstable and undocumented configurable GC parameters, primarily intended for use by GC developers.

As well as using Gc.Tweak.set "foo" 42, they can also be configured in OCAMLRUNPARAM, using the following syntax:

OCAMLRUNPARAM='Xfoo=42'

Additionally, OCAMLRUNPARAM=Xhelp will show the available GC tweaks.
