This is taking 555ms in this profile.  What I was doing was keeping Cmd+W pressed down after having opened a whole bunch of tabs on Nightly.

Kannan, is this profiler overhead?

This is likely due to new code getting compiled all the time in response to these actions. It's profiler overhead, but there is no easy path to resolution at this time. THis behaviour is pathalogical, but so is the use case here.
