I cannot reproduce crash nor hang on 2xXeon x86_64 machine after 100 runs. how long did you
have to wait?

> The test hangs intermittently and should be run in the loop as follows:
>  test=gc.ThreadSuspension; while true; do $DRLVM -cp <calsspath> $test; echo $i
$test; i=$[i+1]; done
> Sometimes the test fails and then hangs:
> -- starting unsuspendable computation --
> -- starting suspendable computation --
> forcing gc after 1 s delay
> FAIL
> gc completed
> Please see stack traces in gc_ThreadSuspension_fail_x86_64.txt attachment for the above
hang on x86_64.
> Sometimes it passes and hangs:
> gc.ThreadSuspension
> -- starting suspendable computation --
> -- starting unsuspendable computation --
> forcing gc after 1 s delay
> gc completed
> PASS
> Please see stack traces in gc_ThreadSuspension_pass_x86.txt attachment for the hang on
x86.
