Hi Glenn,

Thanks.

Increasing timeouts, in my experience, rarely solves these problems (still,
if you suspect one in particular, feel free to adjust it).  It's usually a
case of unusual process scheduling in the ci machine that my code isn't
accounting for.  It'd be better to analyze the code to figure out what
might be happening (Something that I haven't done yet...) Also IIRC there's
a reference  in the test code to a mysterious existing bug somewhere...

Maybe someone with deeper knowledge of Emacs's processes can take a look
too.

Thanks again,
João
