can I kill an ssh connection while updating my OpenBSD box?

["corgi corgi" <corgimax@hotmail.com>]

I have an OpenBSD 3.1 box in my server room.

At my workstation, I have ssh'd into the OpenBSD box using Putty.

Following some instrustions on the internet, I'm updating the OpenBSD box 
using the OPENBSD_3_1 patch branch.

After doing "make clean && make depend && make", a bunch of "stuff" whizzes 
by the screen.

If I kill my ssh connection at this point, will it stop everything the 
OpenBSD box is doing?

If I ssh back in, can I get back to this screen and see all the "stuff" 
whizzing by the screen again?
