Comment:

 Please see my branch `retry-test-network-on-failure` on
 https://github.com/teor2345/tor.git
 It has the following changes:
 * Retry boostrap (configure and launch) once on failure, configurable via
 CHUTNEY_RECONFIGURES or --reconfigures
 * Retry verify every 5 seconds from BOOTSTRAP_TIME (now 20s) to
 MAX_BOOTSTRAP_TIME (60s), configurable via --time and --max-time
 * A separate commit that fixes up the indenting and spacing in the script

 This makes src/test/test-network.sh suitably robust to intermittent
 failures and variable machine speeds. This will ensure that #16953 reports
 actual failures, not transient conditions or slowdowns.

 I have tested it on OS X and Linux.
