Thanks for looking, Adrian,

It'd be great if someone was able to find out more about what's going on
here.   Bandwidth at GHC HQ is always tight, so the more precisely
someone can pinpoint what's happening, the faster we can fix it.  Joel
has done a lot by making a repro case.  Maybe others can help to narrow
it down?

| Hello,
| I haven't followed everything that's happened on the Binary IO
| thread, but has anybody else actually tried Joels code? ..
|  http://wagerlabs.com/timeleak.tgz
| I can reproduce the problem (ghc/Linux), but can't explain it. It
| seems very strange that friggin about with an otherwise irrelevant
| (AFAICT) MVar fixes the problem.
