On my Fedora 11 AMD x86_64 system, it appears the deadlock still occurs
(up to the limit of my patience, ie: several minutes). If I reduce to say
3, I can get the test to succeed sometimes.

Yes, they can. Actually, even the GIL uses them. :-)
On the test side, the case I supplied was low noise for me - I'd
hesitate to do as much compression as you

New submission from Robert Collins robe...@robertcollins.net:
