i'm among (probably many) developers who interested to hear it. i
believe that gtk2hs uses thread where it was initialized as main (this
thread should be bound so it's either main thread or one created with
runInBoundThread/forkOS) and the everything should either run in this
thread directly, or in signal hadlers (that are executed in this
thread) or via postGUISync/postGUIAsync. moreover postGUISync can't be
used inside main GUI thread due to locking

as you may remember, once i proposed to add wrapper that is equal to
id in main GUI thread but equal to postGUISync in other threads. or
even better, wrap all gtk2hs operations in this wrapper
