The test always failed. When I decreased the number of threads in the test
from 5,000 to 1,400 or so, then the tests passed sometimes, and sometimes
failed. Decreasing the number of threads to under a thousand made the test
pass consistently. IIRC, the test failed almost immediately upon executing.

Now, when I tried to rerun the tests against the latest ghc-6.6, ghc.exe is
segfaulting on ffi012(ghci), conc049(ghci), and conc023(ghci):

Unhandled exception at 0x0207fc58 in ghc.exe: 0xC0000005: Access violation.

TX_fail and TX_exn are segfaulting as well. I haven't looked into them yet.
