Description
I can't seem to find any support to control the number of tasks a worker is allowed to process. I am thinking something similar to maxtasksperchild when creating a pool https://docs.python.org/2/library/multiprocessing.html#module-multiprocessing.pool.
Some of my tests use a library the uses gobal data structures that will conflict across tests. Is there an option for one worker per test?

Research direction
The issue names no files, tests, or entry points. Start by tracing how pytest-xdist creates and schedules workers, then compare the requested per-worker task limit with Python multiprocessing's maxtasksperchild behavior. Done means users can configure a worker task limit or one worker per test, with tests covering the setting and its interaction with worker scheduling.
