[PD] GridFlow more usable.

[Mathieu Bouchard]

I found the bug that was causing random crashes especially through
GridFlow's clock.

The change has been applied to GridFlow cvs-current.

I recall several folks here were waiting for this to happen. Well, it has
happened now, so have fun.



GridFlow's tech support hotline ;-) is still:

IRC.FreeNode.Net #dataflow
