Did you try already to define a texrunner-object from pyx, in order to
communicate with tex? I'm not sure whether it will solve your problem, but
at least it should be possible by re-initializing the texrunner to restart
tex,
thus establishing a new connection. Thus, I would propose to try something
like
pyx.defaulttexrunner= pyx.texrunner()
in order to restart tex.
Maybe it works?
