Details:

In fact i think a good way to prevent this would be to make these checks in
shm class constructor shm() and then use something like : if (
$GLOBALS['phpgw']->shm->enabled ) { blah blah...

But this would be rather heavy to do... so i submit this tiny patch allowing
setup to go on even if shmop is not available.

Notice : If shmop is not available the code crashes silently in
class.shm.inc.php because of the @ before shmod_open line 217 : if(!$id =
@shmop_open($key, "a", 0644, 100))

here is the patch :
