In so far as only the CPython interpreter has one, I'd have to say "yes"
to this. It's used to make various operations trivially thread-safe,
which allows large speed gains in the programming.
A long time ago Greg Stein produced a patch that removed the need for
the GIL, but nobody seemed to want to pay the penalty it extracted in
speed reduction, so it languished unadopted.
