isSpace is too slow

In the thread starting http://www.haskell.org/pipermail/glasgow-haskell-users/2007-May/012608.html Neil Mitchell compares the speed is isSpace to C's functions:

C's isspace: 0.375
C's iswspace: 0.400
Char.isSpace: 0.672

The thread contains some discussions of possible solutions.
