Jan's speed post came about just as I was testing some HDL for an
upcoming mixed-signal ASIC, here's the hack-way I've done it:
(requires the extra pytest-xdist plugin)

py.test --dist=load --tx 4*popen//python=pypy
and half the processes when using cosimulation

It's been a killer combination for long-running tests, especially when
using Rackspace instances to keep my main machine free while they run.
 For some reason, running as a module under pypy fails if there are
extra cmd line arguments related to xdist, hence the above
work-around:

"python -m pytest foo.py" and
"python -m pytest -n4 foo.py" and
"pypy -m pytest -v foo.py" work properly, but any options fail with e.g.:
"pypy -m pytest -n4 foo.py"

tox would be better for more formal multi-platform release stuff, though.

HTH,

Dan
