Right you are.
If you want to have "decent event oriented Pascal programming" (i.e. by
using TThread.Synchronize and/or TThread.Queue for handling the issues
the OP requested such as doing blocking I/O in Threads), you need to do
an environment (which can be seen as a "WidgetType" in Lazarus speak)
that calls CheckSynchronize in the main thread and that implements
WakeMainThread to wake the main thread (idle while waiting for a timeout
in CheckSynchronize) by means of the underlying OS.
TTimer can be implemented on top of that as a Graeme "ThreadTimer" or by
other means (I intend to provide a very rough TTimer variant based on
the CheckSynchronize timeout).
