[Lazarus] GTK2 threading

Dear Lazarus developers!
I'm examining the problem disturbing me for years.
GTK2 applications provide thread-safety using internal mutexes passed
And it works.
Pure X-Applcation does so (orders X-messages per-thread) using
XInitThreads at early start of application.
And it also works
But GTK Widgetset uses pure Xlib calls for determining keyboard states.
Xlib thread-safety is not initialized in GTK2 widgetset.
IMO the problem half-way to resolve - either not use Xlib calls (pure
GTK2,3 - it is threadsafe) or make GTK and Xlib interoperable.
Or block GTK calls until Xlib call returned.
with best regards,
