In practice I find that stat calls are a minor performance factor when
compared with database calls so for any fairly dynamic site it's not a big
factor.
However, perhaps a better tradeoff for a production site would be to perform
these stat calls in the parent just before a graceful restart. Then to force
rereading the library files without any downtime the you would just do a
graceful restart, which would recompile all the .pm files and then start
spawning new children with optimal shared memory behaviour:)
I believe Apache::ASP's internal mechanism is capable of this now.
