You're right, it made the particular buildhost happy, nevertheless it
doesn't sound like an enterprise solution to me :-)

It's simply machine-dependent, there is no such thing like optimal value.

I tried 10s and it was still failing occasionally. With 16s it seemed
to work fine in a loop.

SSL handshake is based on asymmetrical cipher, which is computational
expensive. I didn't consider there anything fishy since whole build
takes bigger amount of time on that machine.

From my observation - 10s is not enough, 16s is enough.
