Description

For some reason, recently each Python build has been taking about 15 minutes to run. I speculate this is due to VM thrashing caused by reduced resources on the Travis CI workers, related to the problem I fixed in ARROW-2062.

We should experiment, but it seems like perhaps this can be fixed either by:

• Reducing the size of the Plasma store on Travis CI
• Disabling valgrind in Plasma tests

The slowness could be caused by something else, though, so we should investigate (and have pytest report slow tests in the logs)
