Functionality for collecting fails and retrying specs at the end of execution instead of right there after first fail

[snackattas]

I run selenium tests 60x parallel, and, the system is at its limit during a test run performance-wise.

It would be nice if, instead of immediately retrying the spec upon fail, this gem had the option to retry the failed specs at the end of the process...where there are more likely to be less tests running at the same time

Is that a possibility? If it is, and the committers don't want to add it, if you point me in the right direction, I'd be happy to look at adding it.

I would help with this. If anyone could point us in the right direction, that would be awesome.
