----------------------------------+----------------------------------
On the HP 2013.2.0.0 on OS X 10.6, a program running a worker thread
started with ForkIO and communicating over MVars crashes on exit with this
error message:
out: internal error: stg_ap_p_ret
(GHC version 7.6.3 for i386_apple_darwin)
Please report this as a GHC bug:
http://www.haskell.org/ghc/reportabug
Only with setNumCapabilities 1, though. Works fine with the systems actual
core count (>1).
