Hey Reinaldo!

Yeah, I know (except for #5, I don't know what that is).  Still seems like a
lot of them seem to choose #19 - Slowly Grind to a mystifying Halt or #14 -
Reboot without explanation.  (Although the reboot is probably a watchdog
function reacting to the grinding halt!)

  :-)

PS:  Is it possible that some devs just don't know what to do when the table
is full or nearly full?  I know that these guys are working on SDKs from a
small handful of vendors, but I've never actually seen one or the
documentation that comes with it.
