How do I wait for all threads in an Indy thread pool to finish

I am using Delphi xe 5 for an application which uses Indy to manage my server application

Each client connection gets its own session which is perfect

Now I need to perform several tasks in aysnc way within one of these sessions

When all of these tasks have been completed control can go back to the caller

I am looking into using a local scoped thread pool in my procedure which will place each task to be performed into the thread pool

I have seen the TIdThreadMgrPool which looks perfect

How do wait until all of my threads have finished?

Indy 9's TIdThreadMgrPool component (replaced with the TIdSchedulerOfThreadPool component in Indy 10) is not a general-purpose thread pool. It is designed for use only as the client thread pool for Indy's TIdTCPServer component. There is no option to wait for active threads to finish running, TIdTCPServer handles that internally while it is being shut down.

There are plenty of 3rd party general-purpose thread-pool implementations available for Delphi, such as OmniThreadLibrary. If you were using XE7, you could take advantage of its new Parallel Programming Library instead.
