Resumes a single thread only

When we call resume on a thread, it is better to resume that single
thread instead of calling resume on the manager, that iterates over all
available threads calling resume.

Updates the view when a thread is waiting

In case the main thread is blocked in a permission predicate, the
blocked file is not shown to the user. This fix provides the view update
and thus the blocked file is bring to front.
