[TIP] pytest xdist raise INTERNALERROR occasionally on Windows 2008r2

[Ronny Pfannschmidt]

Hi Baiju,

that looks like a bug you should report on pytest

the problem with the output always being the same seems to be that
its an list of 50 items and something in the middle is different,
for debugging purposes you might want to employ difflib's SequenceMatcher
to print out the difference of those 2 rather large lists
