Too expensive for the acl operation?
{{{
$ egrep _re_ acl/*.[ch]
acl/acl.c:	re = slapi_re_comp( pat, &re_result );
acl/acl.c:	/* slapi_re_exec() returns 1 if the string p1 matches the last compiled
acl/acl.c:	rc = slapi_re_exec( re, realval, -1 /* no timelimit */ );
acl/acl.c:	slapi_re_free(re);
}}}
