Cause a function to be executed by the reactor thread.

Use this method when you want to run a function in the reactor's thread from another thread. Calling callFromThread should wake up the main thread (where is executing) and run the given callable in that thread.

If you're writing a multi-threaded application the callable may need to be thread safe, but this method doesn't require it as such. If you want to call a function in the next mainloop iteration, but you're in the same thread, use callLater with a delay of 0.
