Missing imports of the sys module.

Improvements and fixes for the debugging print outs from the status module.

Fixes for the calls to sys.stderr.write() in the objects of the status module.

The observer objects are now printing out execution information when in debugging mode.

All acquire() and release() calls for the spin_lock and pipe_lock objects now are named.

The name argument is now supplied to these methods.

The Relax_lock object now has much better debugging facilities, and responds to the debug flag.

Renamed the Relax_lock debug arg to fake_lock.

Again this is used to fake the locking mechanism, whereas debugging could be more fine grained.

The Relax_lock object now has a 'name' argument which will be used in debugging.

The pipe_lock locking object is now the special Relax_lock.

This will allow for fine grained debugging.

Renamed the execution lock debug flag to fake_lock.

This is a bit different from the normal debugging and allows a different type of debugging.
