I would dispatch all long-running actions to a dedicated instance of
some "worker" class that gets a request to "do something", starts this
job a thread or external process and keeps track of the progress. Such a

"worker"
can handle multiple requests at the same time so you return an ID to the

caller.
Then you can create your own "please wait" page based on the progress
information returned from the "worker" instance..,...that's the theory
:-)
