To subscribers of the xforms list from "tom wible" <tom@radar.fp.trw.com> :

this may or may not have anything to do with xforms, but since i started using
fl_add_io_callback, i've been getting this errror:

GL: X ext error: major req = 42, minor req = 0, err code = 8
ERROR #93 Error in communication with window server: ERR_WMANIPC

after losing control of my xforms windows(non-responsive, & they don't redraw)
my gl window, howver, remains functional until this error.

i'm using fl_add_io_callback to read the output of a popened tail of a file
(which is my only access to the state of a concurrently running gots
simulation) perhaps the fact that this is a blocking read means i can't use
fl_add_io_callback in this application...

any suggestions would be most appreciated.
