In theory, I am not against.

But: Not all tests can be run in parallel.  DB code is for instance not thread safe.

Given the nature of decorators, it will require extensive checking to make sure that 
tests that rely on the same decorator will be run in the same thread anyway.

Just some random thoughts.
