What error is this specifically? If you have a module-global variable,
it will be accessible from any thread. If you want to access the
variable from multiple threads, you need to protect it with a lock;
see thread.allocate_lock. However, the variable will still be there...

That statement is without any effect: it deletes the local variable
ulist, which is then not further used in this function.
