Yes, it often will & the code already does this if there are no
more empty slots in the table (by default, the table size is 10000
in a large Hugs configuration.)
Exhausting that limit is in my experience a sign that you're
accidentally holding on to too much external state (maybe
at a too fine-grained a level -- this was an issue in an earlier
version of the Com support libraries, for instance.) If you
need to have that many FOs live, upping the limit & recompiling
Hugs is the only way around the problem.
