Synchronization in Experiment class causes contention problems for experiments with many parallel tasks

Description (last modified by gkronber)
The relevant changes have been introduced in ticket #1878 (r8170). To reproduce create an experiment containing cross-validation optimizers. Use multiple workers for each cross-validation and start multiple cross-validations in the experimenter.
This does affect performance of a single algorithm execution, but especially GUI updates are slowed down. One issue is synchronization in handlers that are called through (AsynchonousView).Invoke(). In these handlers it is not necessary to synchronize.
