This is more robust vs. PYTHONPATH containing '' (current directory), which occurs when running under pytest-xdist. Running in a temporary directory is also consistent with how benchmarks themselves are run.
This speeds up the benchmarks by 50+ sec
Disable pytest-timeout, as it appears incompatible with xdist
…in thread Setting signal handlers works only in the main thread. Typically, asv is single-threaded, but when running tests, pytest-xdist doesn't seem to always guarantee the tests are run in the main thread.
This may avoid sending signals to workers, which can bump into multiprocessing bugs on python 2
Use only the currently installed Python version, plus a second version.

Run tests in parallel with pytest-xdist.
Fix timing issues that caused problems with pytest-xdist.
Use
--bench=in tests to avoid running the whole slow benchmark suite.Prefer close+join when using multiprocessing, to avoid some issues on python2 on windows.
Fix test_web:basic_html fixture to work with pytest-xdist.
Add --offline option for running tests without pip/conda downloading.
Pre-download necessary packages before running tests, which also mitigates some issues with conda's parallel execution safety.
