The threads are managed by IIS, PerlIS is just an ISAPI plugin (DLL) that is loaded by IIS into the process that hosts these threads. Note that you still must make sure all modules used under PerlIS are thread-safe because the threads for one application pool all run within a single process. So if you have a Perl module with XS code that stores information in a static C variable, then you still have a race condition when 2 requests are processed in parallel.
