Yes, though I should note I wasn't trying to defend having a
compatibility sysctl or whatever - I think it's clear these apps are
broken.  The python docs explicitly say that the returned string is
just a straightforward transformation of uname, and if the apps read
that carefully they'd realize they only want the first part.

The reportlab example will break for FreeBSD 5 too:

     elif sys.platform in ("freebsd4", "darwin", "mac", "linux2"):

I just happen to watch Mozilla bugzilla so I saw that one go by and
wanted to provide data for the discussion.
