I dont like using START/EXIT events for load/save all data, because it (theoretically, if the data is very much) will be a high load.
load/hsave hash tables data must of necessity. For channels, example, after hadd -m $+(conference,$cid) %# # need check the saved data:
if ($lof($+(channels,/,channel,%#,/,data,.,txt))) {
hload $+(channel,%#) $+(channels,/,channel,%#,/,data,.,txt)
}
and load if exists.. also saving.
but no need using common events for load/save ALL data. IMHO :)
