Comment:

 Ok, I banged on this for a while and can't seem to get it to work right.
 It is easy to make the intermediate cert store and other NSS dbs memory-
 only, but it does not appear easy to clear them at will.

 It looks like Firefox's use of NSS is a crazy minefield of thread-safe and
 thread-unsafe accesses. I have some code that successfully re-initializes
 and clears NSS, but if any tabs are open with SSL pages in them, we get
 random segfaults and crashes.. I'm going to leave the code in the patch,
 but it is not run.

 The pref needs to be set to the desired value at browser initialization,
 and cannot be toggled by Torbutton.
