Description changed by bgamari:

Old description:

> backtraces on stderr. However, GHC's implementation currently only prints
> a backtrace for a single, arbitrary thread. This should be fixed.

New description:

 SIGQUIT is intended to mirror the same signal's functionality provided by
 the JVM. That is, provide a snapshot of a processes' state in the form of
 backtraces on stderr. However, GHC's implementation currently only prints
 a backtrace for a single, arbitrary thread. This should be fixed.
