Two words on this.

The idea is to allow concatenation of "time pipes"
each with possibly a "tap".

For example, in my local NetStreamFfmpeg version,
the PlayHead is fed an InterruptableVirtualClock so
that the buffer controller can "close the time tap"
when buffering, and "open it again" on buffer full
condition.

The PlayHead, in turn, has its own piece of pipe
which is closed/opened on NetSTream.pause.


        SystemClock | NetStreamClock | PlaybackClock

Pushing it on, the SystemClock might eventually be a PlayerClock,
with tap opening/closing on MovieControl->pause().
And PlayerClock might take its time from GnashClock, with tap
opened/closed by SIGSTOP/SIGCONT.

This basically opens up the opportunity to have a
"time-injection-based" core lib, where nothing moves
until you inject some time in the upper-most pipe.
