[py-dev] core design of py.test broken?

[Laura Creighton]

I am thinking about 2 test sessions running simultaneously, one checking that all tests pass
with python2.3 and one with python2.4 

We would like if a running test, trying to do the 'build this in SetUp', found
that the thing was _already there_, waited until that particular area was free
to use.  Else they could collide with each other.  Do we have a way to communicate:
BUSY:  stay out until I am done?
