lgtm, though I thought we still wanted to make delay_tcp_race the default.

Hi Ryan,
  Will submit another CL which makes delay_tcp_race as the default after this CL
lands.

  I had the following CL (which enabled delay_tcp_race as well as reverted). 
  Thought if I do revert first and then add back code that makes delay_tcp_race
as
  the default, it may make it easier to review.

thanks
raman

Abandoning this CL because "Revert Patchset" wasn't able to revert changes
to net/quic/quic_network_transaction_unittest.cc. Reverted the changes to 
this file manually in https://codereview.chromium.org/1977303002/
