I think I found it. Before, I was dynamically loading function pointers
to XOpenDisplay and XCloseDisplay in the main thread, and passing them
to the worker thread as user data.  By deferring the calls to
dlopen/dlsym into the worker thread itself, the segvs go away (I'm not
sure -- it's hard to debug threads other than main in cygwin -- but I
*think* the function pointers became invalid in the worker thread
context, in the previous scenario).

So, give r20 a shot. (mintty is still invisible -- but at least run2
doesn't appear to segfault).
