Subject: [ruby-core:23479] Re: [Bug #1471] "Mutual join" deadlock detection faulty in 1.8.6 and 1.8.7


I don't dispute the analysis either, but...
I cannot seem to duplicate this bug in 1.6.8, 1.8.6-p287 or 1.8.7-p72

Is it specific to just the patchlevels mentioned?
Is it likely to be platform specific?
(I'm testing on x86 32-bin Linux)

When I run the mutual_join_bug script, it consistently returns without
outputting anything.
