The 'other' implementation is the win32 implementation, and it is in place.

FPC does not decide anything. The pthread library decides this.

We totally depend on the pthread implementation.

We'd like to have a native 100% FPC implementation, but none of the
core developers currently has time to look into it.

If you are knowledgeable in this area, we would HUGELY appreaciate
it if you could create a 100% FPC implementation. It would resolve
many problems :-)
