are silently ignored. OldTime is unified with the old timeout
and then timeout is set to NewTime. NewTime is of
the form Seconds:Milliseconds. A non-negative real number, seconds, is
also recognized. The default is 0.250 seconds. This timeout is thread
local and is not inherited from its parent. New threads are
initialized to the default.
Note: The synchronous behavior afforded by in/1 and rd/1 is implemented by periodically polling the server. The poll rate is set according to this timeout. Setting the timeout too small may result in substantial network traffic that is of little value.
