Well, I've just returned, but have several hundred emails to plow through
to see what else happened while I was out.  Have any of these benchmarks
been run with the bash-3.0-2 experimental version?

Currently, bash-3.0-2 dynamically links in libintl and libiconv (along
with at least sed and coreutils, which is a good reason that these
libraries should be made part of the base packages).  Does dynamic linking
affect the time for a fork() to take place, positively or negatively?
Also, I am still waiting for an updated libreadline6 package before bash
can dynamically link against libreadline as opposed to its own static
version of readline.  And it will take some time before I can audit the
bash source code to see if there are any fork/exec pairs that can be
rewritten with a spawn idiom, to see if that offers any speed improvements.
