InetAddress.isReachable fix ETA

[Yuval Lombard]

Hello team,

I had issues with subscribing to the net-dev, and now was able to resolve
it, so now I am following up on this again.

A bit of context to add to the query about the InetAddress.isReachable()
issue I have posted.

It seems my app underperforms when enabling InetAddress.isReachable()
probing of multiple network devices (3-4K devices) with VT, and introducing
a deliberate network traffic delay.
With PT the issue seems significantly less severe
