I don't think that's as practical as you think. You need something like 
FreeLibraryAndExitThread(). You need a function to signal the end, and 
actually exit without returning to the caller, and it needs to be in a library 
that will *not* be unloaded.

Save for creating a small shared object with just the one function, that you'd 
dlopen() manually and never dlclose(), I don't know how to achieve it.

Ah, right.
