The ptr gets globally unmapped by withMappedBuffer though.

Yea.

Maybe you could do like the ByteString library and export things like 
this from an "internals" module. 
http://hackage.haskell.org/packages/archive/bytestring/0.9.1.4/doc/html/Data-ByteString-Internal.html

Or just separate the package into a direct C-API translation (with some 
haskell style error handling), then build a higher level haskell API 
ontop of it (withXXXX functions, added type safety, etc) - maybe even as 
a seperate hackage library.
