Automated g4 rollback of changelist 235365603.

*** Reason for rollback ***

Fixed upstream. The original webchannel change should be safe to roll forward.

There are changes relative to the original cl/235186114 (a2daa5ffd).

*** Original change description ***

Automated g4 rollback of changelist 235186114.

*** Reason for rollback ***

Breaks some development workflows.

We're looking into the root cause, but it's likely to take non-trivial investigation.

*** Original change description ***

Use async.run to schedule the next func call instead of setTimeout(0) to avoid throttling in background tabs.

RELNOTES: improved webchannel responsiveness in background tabs.
