threadsafe needed

[John Meacham]

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.
