I'm not sure I follow you here. The seperations I see as a
possibility is for synchronization types and the thread
creation/manipulation type(s) to be seperated. However, this
seperation makes sense only as a stop gap approach for developers
only interested in making their libraries "thread safe". With out
threads the synchronization primitives are pointless, and with out
the synchronization primitives it's very difficult to use threads.
It's only useful to stop gap in order to allow developers to write
libraries that will be "thread safe" when the users write programs
using the libraries in code that uses native threads. We've seen a
couple of libraries already considering this, including a submission
that uses it's own synch primitives as a temporary solution to the
I can see submitting the two components at seperate dates, but they
are too tightly coupled to truly be seperate libraries, I think.

This differs from the stop gap approach how?
