[pytest-dev] junitxml incremental output writing

[Ronny Pfannschmidt]

Hi Floris,

an incremental writer has to continuously update either the 
pre-overstretched xml header of the report or continuously rewrite the 
file at once.

An implementation would be tricky and need someone to dedicate to it to 
weed out the detail ussues that will invariably crop up.

Another approach could be to just write the xml report parts of each 
item into a junitxml.parts file and
at the end of the test to just recombine the file with the enclosing xml 
element.

I think people that care about it should come up with it.
