set -euxo pipefail
rm -rf venv1 venv{2..10} log{2..10}
virtualenv venv1
venv1/bin/pip install git+https://github.com/pypa/virtualenv@rewrite
seq 2 10 | xargs -P8 --replace bash -c 'venv1/bin/virtualenv venv{} -p /usr/bin/python3.6 -vv >& log{} && rm log{}'

I expect this to block for a reasonable amount of time (maybe max 60s) and succeed in creating the virtualenvs, the logging around locking appears to be broken

$ bash t.sh 
+ rm -rf venv1 venv2 venv3 venv4 venv5 venv6 venv7 venv8 venv9 venv10 log2 log3 log4 log5 log6 log7 log8 log9 log10
