According to the documentation, the Haskell implementation of Handle
should implement single writer/multiple readers locking but the current
implementation doesn't work under Windows. This commit fixes this using
'_sopen' function instead of 'open'. The former allows to implement system
level locking on Windows. The changes doesn't affect other platforms.
