i have seen an option in phpmyadmin, that sets the maximum php script execution time and
titles this to be the maximum query time.
now what happens when php is terminated while waiting for a query? i guess, mysql server
connection is terminated. and is it right that mysql aborts the query execution at this
so i could do this in any other program, too, i guess. just terminate the connection after
a given time and now we have our maximum execution time.
of course, we get no result back then, but it wasn't finished anyway.
