New description:

 Anything that can be done using pywin32 can also be done, a little more
 klunkily, using ctypes. Currently we depend on pywin32 directly to get
 disk stats at [source:src/allmydata/storage/server.py at 4595#L177], and
 indirectly via Twisted. Twisted depends on it only for {{{spawnProcess}}}
 in
 [http://twistedmatrix.com/trac/browser/trunk/twisted/internet/posixbase.py?rev=29163#L331].
 These dependencies could be easily eliminated, simplifying installation on
 Windows.

 (We ended up not needing a change to Twisted.)
