test case

Just extract the zip and start "mono tinyhost.exe 50" (for 50 web app
restarts). It's a variation of the test case from bug 323430.

Even with a GC.Collect() after every restart, quite a few thread handles are
being held until the tinyhost.exe app itself finishes.

We've got Mono/mod_mono from SVN running on two servers. Even without app
restarts, the Mono crashes after three or four days due to all thread handle
slots being used up.

System.Web wakes up every 15s (timeout manager) and 60s (cache expiration
check), continuously consuming thread handles.
