James M Snell 98e54b0bd4 meta: restore original copyright header
A prior io.js era commit inappropriately removed the
original copyright statements from the source. This
restores those in any files still remaining from that
edit.

PR-URL: https://github.com/nodejs/node/pull/10155

Note: This PR was required, reviewed-by and approved
by the Node.js Foundation Legal Committee and the TSC.
There is no `Approved-By:` meta data.

/*
* This test makes sure that non-integer timer delays do not make the process
* hang. See https://github.com/joyent/node/issues/8065 and
* https://github.com/joyent/node/issues/8068 which have been fixed by
* https://github.com/joyent/node/pull/8073.
*
* If the process hangs, this test will make the tests suite timeout,
* otherwise it will exit very quickly (after 50 timers with a short delay
* fire).
*
* We have to set at least several timers with a non-integer delay to
* reproduce the issue. Sometimes, a timer with a non-integer delay will
* expire correctly. 50 timers has always been more than enough to reproduce
* it 100%.
