[issue7753] newgil backport

[Marc-Andre Lemburg]

Marc-Andre Lemburg <mal at egenix.com> added the comment:

On second thought, you're right: while sys.setcheckinterval() could
be made to work with the switching interval, sys.getcheckinterval()
could not be made to return anything useful.

Still, please have a look at the other issues mentioned. They
apply to new GIL in general, regardless of whether implemented
in 3.x or 2.7.

It would also be interesting to see the affect on other threaded
applications, not just the "benchmark" mentioned on the python-dev
thread.

Since there aren't all that many Python 3.x applications in the wild,
it's probably a good idea to check in the patch and then run a few
Python 2.x apps with and without it.

How does pybench react to the patch ? It's single-threaded at the
moment, so a good test of how a single-threaded application would
behave with the patch.

Thanks,
