Sure.

Well, think about the implication of that limit: you basically limit
the number of concurrent sessions you can handle. Your servlet
container/ load balancer would be a better place to impose things like
that.

Do you really have a limit on how many files can be created? You
typically want to limit the number of active file handles at any given
time, and I think that is already part of the package. To limit the
number of files/ directories strikes me as on odd thing to want.
