MaxOnionsPending questions

[Scott Bennett <bennett@xxxxxxxxxx>]

     The tor man page says,

	MaxOnionsPending NUM
	       If you have more than  this  number  of  onionskins  queued  for
	       decrypt, reject new ones. (Default: 100)

Does "onionskins" in this context mean cells or cell payloads?  What is a
typical high water mark for the number of onionskins actually in a decryption
queue at one time?  Under what circumstances?  How can one find out what the
actual high water mark is for one's own tor server?  Is there a way to reset
the current high water mark to 0, so that one could find out usage levels on
a periodic basis?
     Thanks in advance for any answers or clues.
