Not off-the-shelf, but there are third-party modules that'll
load and unload .so s in a running server.  Of course it's a
big security issue.  And, also for security reasons, you can't
do everything a module can do: the running server has dropped
the system privileges it had at startup.

IIS had Nimda, codered, et al.  Apache, with three times IIS's
market share, didn't.  Apache will let you shoot yourself in the
foot, but unlike IIS (or PHP) it won't hand a loaded gun with no
safety cache to an admin who has no clue about using it.
