Only if your machine is slow (i.e., only if the selection service isn't
running by the time you first do your selection).

No, it's not; keyboard and mouse events come up from the serial ports (or
parallel ports, for those of you who still have Sun-1s...) through the
appropriate line discipline/streams module, and end up in kernel code that
distributes the events to the appropriate process through a "/dev/winN"
device.  The section service is an RPC-based service that, not
surprisingly, manages selections.  (It does *NOT* handle the mouse button
events that indicate a selection; the application does that.  This appears
on page 96 of the very description you cite in the SunView 1 System
Programmer's Guide.)
