I have committed the following change to the coverage-poker-network branch
that attempts to solve the timing problem with these coverage tests:
http://svn.gna.org/viewcvs/pokersource?view=rev&rev=6008
I'd be curious for others' review of this change (also attached a patch,
copyrighted by me and licensed AGPLv3-or-later).
I think these changes address the timing issues. The tests work for me;
I'm running them over and over again now to see if I can generate a timing
issue.
