you and others are thinking only of modern doors written in the 90s that do
handle this on multinode bbses... there are, however, older doors that have
not been updated that do not... some of those doors are or were fairly
popular... unless i'm mistaken, daryl has several hundred doors on his
system and some of them are quite ancient and do not have this
capability... attempting to trap this in a script file is ok but there is
still the possibility of two or more nodes still executing the door if they
check the inuse flag file at the exact same time... a race condition it is
called... i've always wished that bbses had this ability and have it in the
list of things to be implemented in my own bbs code if/when i ever get back
to it... doing it in the door itself is better than in the script but
there's still the race condition aspect to deal with... besides, it is only
a feature request...
