Yes, I noticed that the platform specific stuff doesn't get covered, of course. It's very easy to do, if there's any way to get the coverage database from a central location (or send it back to a central location).
It might be interesting to run coverage analysis -- either figleaf or Ned Batchelder's module[0] -- once a week on select buildbot machines (one linux, one windows, one mac, or some such) and make the coverage databases available via something like a downloadable static file. Then anyone could download those files and do Interesting Things with them.

[0] I'm sorry, I don't know how Walter Dorwald generates his coverage; if it's OSS, then it'd be better to use because it shows C code coverage as well.
p.s. Here's the diff for regr_test:
