threadsafe needed

Quite a few foreign calls in the library are missing threadsafe in their declarations. if this could be fixed by 6.2.2 that would be great. in particular system, rawSystem, and DNS lookups are important to be able to do concurrently. Also, is there plans for a threadunsafe? which seems like it would be a much more common case than threadsafe and should be much easier to implement since there is no chance the haskell runtime can be called from a thread it didn't expect.
