Segmentation fault in the single pass demo

[dvmorozov]

LCL creates a few processing threads under Linux even for simplest application. This somehow causes failure when event handler creates separate thread and leaves it running. Under Windows only single thread is created and the issue is not reproduced. The issue is not reproduced when event handler waits for termination of all created threads. As a workaround TRunner.Wait is called. Otherwise probably architecture should be changed.
