bug#32764: Somne flymake tests seem unstable

[João Távora]

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

I've seen some flymake test failures like the following a few times.
Perhaps some timeout needs to be increased.

    Test included-c-header-files condition:
        (ert-test-failed "Some backends not reporting yet (flymake-cc)")
       FAILED  4/9  included-c-header-files (10.545006 sec)

    Test perl-backend condition:
        (error "Selecting deleted buffer")
       FAILED  5/9  perl-backend (0.289559 sec)

    Test recurrent-backend condition:
        (error "Selecting deleted buffer")
       FAILED  6/9  recurrent-backend (0.005780 sec)

    Test warning-predicate-function-gcc condition:
        (ert-test-failed "Some backends not reporting yet (flymake-cc)")
       FAILED  8/9  warning-predicate-function-gcc (5.444343 sec)
