 We shouldn't modify any of the data structures passed to
 networkstatus_getinfo_by_purpose(). But the current design modifies the
 running flag in the GETINFO.

 The patch I'm about to post makes sure we don't accidentally modify any
 more of the data structures.



 Thanks to komlo - the patch was her idea, and she helped create it.
