You can prevent heap compaction:
http://caml.inria.fr/pub/docs/manual-ocaml/libref/Gc.html#TYPEcontrol
mutable max_overhead : int; (* Heap compaction is triggered when
the estimated amount of "wasted" memory is more
than max_overhead percent of the amount of live
data. If max_overhead is set to 0, heap
compaction is triggered at the end of each major
GC cycle (this setting is intended for testing
purposes only). If max_overhead >= 1000000,
compaction is never triggered. Default: 500. *)
Use Gc.set to change those parameters.
Best wishes,
d.
PS: I think Lablgtk prevent heap compaction for similar reasons.
