That's actually what I tried first, but in this particular situation
(ghc-6.4.1 / fps-0.7), PS apparently isn't exported?
The CStringLen approach works, except that the allocated data doesn't
get garbage-collected. Just for the sake of experiment I tried a regular
CString with packMallocCString, and that didn't leak nearly as much memory -
but still some, in a simple loop where "pack" doesn't leak anything.
