GHCI/FFI/GMP/Me madness

[Abraham Egnor]

Ah, that triggers the bug for me as well.  Oddly, calling
System.Mem.performGC once isn't enough, but twice is:

Ok, modules loaded: Main.
*Main> mpz_new
*Main> System.Mem.performGC
*Main> str_test
1

vs.

Ok, modules loaded: Main.
*Main> mpz_new
*Main> System.Mem.performGC
*Main> System.Mem.performGC
*Main> str_test
