Not bad.  "Synchronous operation" ~= "synchronous exchage".  What
about saying something about how strictly to interpret "at the same
time", or some model that permits such?  Clearly, if I wait ten minutes
for your response, I'm participating in synchrony, and we're not
requesting and responding at the same time.

It seems to call for an awful lot of stuff happening "at the same time",
a concept difficult to conceive of unless you take that to mean within
the same time interval.  If you do that, then there's the length of the
interval to look at.

What do you think about, simply:

Synchronous operations may fail by "timing out" i.e., taking too long.
For asynchronous operations, "timing out" is undefined.
