The GIL is an implementation specific issue with CPython. It will not be
removed in CPython for the forseeable future, but you can already get a
GIL-free interpreter with Jython and IronPython. AFAIK there are plans
to remove the GIL in PyPy.
According to the last PyPy release announcement, they're running at
about half the speed of CPython, and have a preliminary JIT that can
translate certain integer operations into assembly, and will be expanded
upon in future releases. If you're looking for a progressive alternative
to CPython, I'd keep an eye on that project ;-)
