I haven't seen any particular problem with using UNIX operating system
domain sockets on an 835.  Could you send me a stack trace?  Are you
using our libX11.a, or one compiled from the MIT distribution?

I'd be _very_ surprised if the problem could be caused by using R3
toolkit and widget libraries.  Does your application have any signal
handlers, and if so do any of them do any X-related operations?
