[fpc-pascal] Xlib Threads

[Brian]

All the Xlib documentation seems to imply that threads can be used , however
if I attempt to put XNextEvent() or XPending() in a thread , the rsult is a
GP fault . The error message suggests using XInitThreads() but it still
generates a GP fault.

Tried using XlockDisplay() and XUnlockDisplay() in the thread but still get
a GP fault.

X Error of failed request:  BadLength (poly request too large or internal
Xlib length error)
  Major opcode of failed request:  100 (X_ChangeKeyboardMapping)
  Serial number of failed request:  20
  Current serial number in output stream:  35

X11 code which causes the problem in the thread :

  
   NewEvent := Xpending(TheDisplay) > 0 ;

   if NewEvent then 
     begin
      XNextEvent(TheDisplay, @myevent);
       KeypressedX :=  myevent._type = keypress ;
     end;

Any suggestions are welcomed. Thanks in advance.
