Yes, and thanks for bringing it up.  

Robert mentioned a tool used by optparse which preprocesses during
installation several modules into one large module.  Loading one large
module from bytecode is allegedly much faster than loading it piece by
piece.

However, that may be true only if we actually end up using most of the
code; for many invocations we possible will not.  Also preprocessing it
in this way is just a bit kludgy.
