Is there an option to be serial cross-process?

[gilescope]

I'm looking at trying to get cargo to run test crates in parallel processes ( rust-lang/cargo#10052 ). It would be cool if there was an option for the attribute to be cross-process serial by locking on a system mutex.

There isn't currently, but there could be. This is the same as the doc test issue (#30) and I've talked a little bit about possible options there. It's on my "I should do this at some point" list, but hasn't gotten far enough up yet. Patches welcomed!

ok - let me try and get the cargo pr ship shape first.

#43 should solve this
