Xlib: unexpected async reply (sequence 0x47)!

[Hassan Aurag <aurag crm umontreal ca>]

 Hi,

The subject with the exclamation and all is the message I get 
sometimes when using the software I code. I suspect it has to do with 
threads that I use for very stupid things like making fifos so that 
processes can communicate but in truth I have no idea what this beast 
is.

 So what the heck does it mean to have:
Xlib: unexpected async reply (sequence 0x47)!

Thanks in advance,
