#C Herschel to 'swimmer' (channeled switch engine) and
#C swimmer-to-Herschel conversions, in an odd-period loop (p9995).
#C Signals can follow each other with a minimum spacing of 629 ticks.
#C This could be reduced to 251 ticks with known technology at the
#C H-to-S end, at some minor cost to the converter's overall size --
#C but the current S-to-H end will need 600+ ticks to recover anyway.
