Are dets:to_ets/ets:to_dets synchronous.

[Jeff Einhorn]

I was wondering if the commands dets:to_ets and/or ets:to_dets are
suppose to be synchronous.  At a glance it seems that when I try to read
a large dets table from disk and convert it to an ets table my function
seems to return before they are actually done.  If the dets:to_ets
and/or ets:to_dets functions are not synchronous is there any way to be
notified when they are done?
	thanks for your time,
