Yay!! After more googling for "php background processing" and lots of 
testing, I found a working cross-platform background-processing method 
using functions popen() and pclose().  (Never heard of those 
functions!)  It relies on the command line ampersand concept.

Explained here:

See below for the heart of the idea.  Now if we can just spread the 
word--this is a question that has come up on a zillion forums!

if (is_windows()) {
  // windows uses "start /b"
  pclose(popen('start /b ' . $call, 'r'));
} else {
  // *nix uses "/dev/null &"
  pclose(popen($call . ' /dev/null &', 'r'));
}
echo "<p>Called &quot;$call&quot; without waiting for a return value</p>";
