To be pedantic, the finally clause will always run, *provided* the code
in the try block itself exits (either by finishing or by raising an
exception). If the try block never exits, the finally block never runs.
# Don't try this at home.
print "Can't stop this!"
print "This never prints"
The only way to exit the loop is to hit it with a hammer (kill it from
outside Python), in which case the finally block never gets to run.
