       Ok.  It is basically a stack depth of 127, which should be sufficient.

      But what does happen if it is reached?  does the last one just not execute?

     Yes, that's what happens (and you also receive a warning message on the 
server console).

     That could happen, but because of script stack limit, an infinite loop would 
be very difficult to be run that way. Infinite loops are difficult to 
prevent; that's one of the reasons that made me put the stack limit on 128, 
not higher. The other reason is of course memory requirement, although script 
data tend to be small. 
(short note: I fixed the maximal index of the stack to 128, giving a total of 
129 stack levels, not 127 as I said before).

      code handles some things poorly (like many spell effects).
     
     I definitely agree with you.
