Yes, that is necessary since GNAT tasks are mapped onto OS/2 threads.
You also should create a window in the task that will execute the
messageloop or OS/2 will put messages in the wrong queue. This makes
creating multithreaded applications more difficult than it should be.
Unfortunately this is an OS/2 limitation.
At least using Ada you can encapsulate these things in a package with
a clean interface.
