Occasionally, I need to modify an already set value, which needs de-allocation. This right now seems to require a call to ldap_pvt_thread_pool_getkey() to get the old value first, followed by a call to ldap_pvt_thread_pool_setkey(). This requires running twice through the list of keys (not much a hassle, but not a clean interface either). I see two options: 1) let ldap_pvt_thread_pool_setkey() call the free handler, if defined, passing the old value if not null 2) change the API of ldap_pvt_thread_pool_setkey() so that it returns the old value, if passed a non-null pointer to hold it. Option 2 is more intrusive (requires multiple changes to existing code) but possibly more versatile. Comments? p. Ing.
