Thank you, that fixes the issue for me.

FWIW, in the end, the search is still slower as before, by a factor of 5
or so.  But I had found .8 only by trying - if the gc implementation has
been changed, maybe some other value works better now.

I think I'll rewrite my use case to use hash tables instead, that should
be more efficient (less garbage).


Thanks,

Michael.
