Jeff Dike 5f4e8fd08f [PATCH] uml: fix thread startup race 
This fixes a race in the starting of write_sigio_thread.  Previously, some of
the data needed by the thread was initialized after the clone.  If the thread
ran immediately, it would see the uninitialized data, including an empty
pollfds, which would cause it to hang.

We move the data initialization to before the clone, and adjust the error
paths and cleanup accordingly.
