New issue 641: MemoryError when writing junitxml for large test suite
https://bitbucket.org/hpk42/pytest/issue/641/memoryerror-when-writing-junitxml-for
Michael Howitz:
In a large project (> 3500 Tests) we get a MemoryError when writing the junit

(The host is our Jenkins CI server with 4 GB of RAM and 3 GB of swap.)
