limiting rewrite global variable scope

["Stephen Brandon" <stephen@brandonitconsulting.co.uk>]

Hi, 

back-ldap 

I have just discovered that global variables in rewriting are remembered 
between results, if more than one result is returned from a search. 

I would really like to be able to start a fresh set of variables for each 
result, to prevent "leakage". 

I tried to do a rewrite_var_delete at the end of ldap_send_entry, but it's 
getting me into locking problems -- and in any case, I'm not sure that I 
should be deleting the avltree entirely - I just want to empty it, not 
destroy it. 

Can anyone offer any advice? 

Cheers,
Stephen Brandon
