I like the general idea that stuff implemented in C is just a thin interface
layer on top of existing system services and that higher level protocols are
implemented in Python where there's no overriding need for them to be
written in C.  This fits that model, at least to a first approximation.  The
sys.exitfunc variable functions pretty much like calling the atexit(3)
library call (though that's not how sys.exitfunc is implemented), and the
atexit module provides a protocol that dictates how that mechanism is used
in a cooperative setting.

There's almost certainly no performance reason this code should be
implemented in C.  It's going to be easier to maintain and enhance if
written in Python, and won't add size to the interpreter for those
programmers who don't use it (or don't use other modules that do).
