# Since changing this, I usually see at least a few retries, and sometimes more
# than twenty, before the check for HL_FILE1 succeeds. The 'ls' is also
# necessary, to force a name heal as well as data. With both that and the
# 'stat' on $M0 being done here for every retry, there's no longer any need to
# have them elsewhere.
#
# If we had EW_RETRIES support (https://review.gluster.org/#/c/16451/) we could
# use it here to see how many retries are typical on the machines we use for
# regression, and set an appropriate upper bound. As of right now, though,
# that support does not exist yet.
