Compaction delay
From MLDonkey
Sets the period (in hours) between two forced [ocaml garbage collector] memory compactions.
Doing a memory compaction from time to time should prevent any long term memory fragmentation.
On the other hand, compacting memory can be a lengthly process, so you may see MLdonkey \"freezing\" for a moment when it happens.
Remark: mem_stats also forces a memory compaction so it can report accurate results.
