Fascinating video! I don't do a lot of multithreaded programming on
Python but it's good to know what causes the performance problems, it
was particularly interesting for me to learn about priority inversion.
There's a link under that video to an interesting post on python-dev
about reworking the GIL:
http://mail.python.org/pipermail/python-dev/2009-October/093321.html
Apparently he manages to get some performance improvement by releasing
the GIL using a fixed time period (instead of interpreter ticks). This
is from October 2009, I don't know if this made it into Python yet.
Cheers
