The js test may hang when stepdown is executed during ShardingTest initialization, for example from jstests/libs/override_methods/sharding_csrs_continuous_config_stepdown.js hook in sharding_csrs_continuous_config_stepdown suite, see trace below.
ShardingTest has to stop such hooks during initialisation and resume when it's ready.
