Unless I'm doing something wrong, it isn't working like that. I 
currently have this code for testing:
local function get_mutex(state)
  return nmap.mutex("RONTEST")
end

If I use that function in two different places, I seem to get different 
results (judging by the error, "Do not have a lock on this mutex"). I've 
put debug statements all over, and I don't think I'm doing anything weird.
I tried storing it in the registry instead, and that seemed to work. I'm 
storing the mutex itself, not the string.
I'm wondering whether this is an artifact of how Lua handles strings, or 
if there's a bug in the Mutex code? I can do more testing, if anybody 
wants, but it seems to be working now (albeit a little roundabout).
Ron
