Shared libraries do slow down the startup of processes linked with them, but
we have been improving the VM system to mitigate some of the problems. V1.1
will have many improvements over the stock VM system (part of which will
*help* the startup.)  V1.2 has even more improvements, but still the additional
mmaps and friends (and the user-level startup) do hurt.  V1.1 is
problematical, I cannot add some of the improvements that are itching to be
added.  Mmap and friends will be *very* fast in V1.2!!! :-).
