I'm experimenting with a fix now. The problem may be that the same conn

Howard, many thanks for spotting this issue, it was really becoming a
nightmare. I've ported your fix to back-meta and added some bind
testing to concurrency testers (test007, test035 and test039). They
seem to run fine, but I seldom see any hang, so I really need to repeat
the tests a lot of times. If anyone who is often seeing hangs could
step in and stress HEAD a bit... (tests035 and test039). If it works,
we can likely close ITS#4246, 4247 and 3832.
Apart from fixing few small issues in the tester programs, I've
repeatedly run test036 & test039 on a few different architectures,
including dual CPUs, without any of the relevant issues (neither hangs
nor loops). I wouldn't consider my tests exaustive though, just my own
2c.
I ran test039 repeatedly for a couple of hours with no hangs on my
dual-core x86_64 Linux system. I'll try looping the other tests as well.
I've been unable to reproduce the hang on my 4 CPU Solaris 8 system.
