The two integer parameters "used" and "max" passed to alloc_custom are
controlling how fast the custom blocks are reclaimed by the GC, as
explained in section 18.9.2 of the manual
(see http://caml.inria.fr/pub/docs/manual-ocaml/manual032.html).
I don't think that calling caml_gc_full_major by yourself is a good
idea. You should trust the GC; it will eventually reclaim any block
that is not referenced anymore.
Hope this helps,
