Great!  Any changes you could suggest
to /rescue based on that experience?

Probably.

Profiling the dynamic-link code would probably
also help.

NetBSD made this change a long time ago,
and Luke Mewburn observed that switching
/bin to dynamic linking prompted a lot of
people to study and optimize the dynamic
linking code, with big wins for programs
like Mozilla and OpenOffice that rely heavily
on shared libraries.
