LGTM! Thank you!

multiple_pilots and specifically pilot.00001 only fail with:

 /home/runner/radical.pilot.sandbox/rp.session.fv-az410-569.runner.019649.0000/pilot.0001//bootstrap_0.sh: line 912: /home/runner/radical.pilot.sandbox/rp.session.fv-az410-569.runner.019649.0000/pilot.0001/bin/activate: No such file or directory
 39 Loading of virtual env failed!

Looks like it is a race condition, and pilots on the same machine can interfere with each other

from bootstrap_0.out

VIRTENV           : /home/runner/radical.pilot.sandbox/ve.local.localhost.1.42.0
/home/runner/radical.pilot.sandbox/rp.session.fv-az410-569.runner.019649.0000/pilot.0001//bootstrap_0.sh: line 1595: cd: /home/runner/radical.pilot.sandbox/ve.local.localhost.1.42.0: No such file or directory
VIRTENV normalized: /home/runner/radical.pilot.sandbox/rp.session.fv-az410-569.runner.019649.0000/pilot.0001

and this does from here

radical.pilot/src/radical/pilot/agent/bootstrap_0.sh

Lines 1594 to 1596 in 7a4b73e

	mkdir -p "$VIRTENV"
	VIRTENV=`(cd $VIRTENV; pwd -P)`
	rmdir "$VIRTENV" 2>/dev/null

and it is possible for some pilot to have incorrect VIRTENV env variable
