TCP_IGNOREIDLE revisited

 I'm working with a 40GigE mesh where the average RTT is on the order
of 10s of microseconds. Consequently, any application idle periods
result in poor measured application latency because the congestion
window is constantly being reset.

I know that this isn't a common use case, but it's clear that there
are cases where this is a problem.

I think John's response to claims that the internet would melt sum it up best:
"The problem with this argument is Linux has already had this as a
tunable option for years and the Internet hasn't melted as a result."
