This behaviour is similar to JVM, it exists when all non-daemon threads terminate.
CSC has nothing to do with it (hence there should not be any explicit IL code to handle this),
it's a runtime engine property.
This is actually documented in ECMA docs for System.Threading,
see info on background/foreground threads.
