A small helper class which blocks an asynchronous operation (e.g. a TDEIO request)

Example:
...
Synchronizer mSynchronizer;

connect( job, TQ_SIGNAL( result( TDEIO::Job * ) ),
TQ_SLOT( slotResult( TDEIO::Job * ) ) );
mSynchronizer.start(); // will block here until the slot was called
...
void slotResult( TDEIO::Job* )
{
mSynchronizer.stop();
