It only cost you memory on the server side - there is practically no 
performance hit.  However, running out of open_cursors could be a sign 
of incorrectly coded applications, that would open and never close a 
cursor.  You therefore need to keep an eye on this - v$open_cursor may 
be of interest.

Thanks, Bj�rn.
