Marc Mutz b4689401a5 tst_QThreadPool: don't deadlock when a cancel() test fails
We keep the runnables from finishing by having them block
on a QSemaphore::acquire() call inside run().

If we fail a test that precedes the call to sem.release()
further into the test, the early return will cause the
thread pool to be destroyed, which will then attempt to
wait for the runnables to finished, which, in turn wait
for the semaphore to be released.

-> dead lock

Fix by introducing a RAII object to release the semaphore
with a sufficiently large number to unblock all runnables.
That number will in some situations be too large, but that
does not matter.

This directory contains autotests and benchmarks based on Qt Test. In order
to run the autotests reliably, you need to configure a desktop to match the
test environment that these tests are written for.

Linux X11:

   * The user must be logged in to an active desktop; you can't run the
     autotests without a valid DISPLAY that allows X11 connections.

   * The tests are run against a KDE3 or KDE4 desktop.

   * Window manager uses "click to focus", and not "focus follows mouse". Many
     tests move the mouse cursor around and expect this to not affect focus
     and activation.

   * Disable "click to activate", i.e., when a window is opened, the window
     manager should automatically activate it (give it input focus) and not
     wait for the user to click the window.
