As usual, there were a bunch of other improvements and bugfixes
scattered throughout the source tree. A search through the CVS change
logs finds there were 421 patches applied and 413 bugs fixed between
Python 2.3 and 2.4. Both figures are likely to be underestimates.
Some of the more notable changes are:
