Problems with drawing area

[Dani Mezher <dany mezher fi usj edu lb>]

    I am writing a graphical interface for a parallel numerical
application. My interface receives numerical results via a socket from a
cluster of workstations. My socket handle plots the results on a drawing
area (mirrored on a pixmap in the XServer). The FrontEnd might receive
multiple plot requests simultaneously. Sometimes, my application freezes
(especially when I'm performing some window operations on the drawing
area(resizing, refreshing,...). Is there any problems in the drawing
area widget?? Is it re-entrant and thread safe?
