Tom 68abd1cb29 Kernel: Fix SharedBuffer reference counting on fork 
We need to not only add a record for a reference, but we need
to copy the reference count on fork as well, because the code
in the fork assumes that it has the same amount of references,
still.

Also, once all references are dropped when a process is disowned,
delete the shared buffer.

Fixes #4076
