Rather than restarting josm:

Upload->Changesets->Upload to a new Changeset

The old changeset will time out and you can upload to new changeset(s) 
from there on.

Don't know about a config setting but if you have the Selection panel 
open on the right hand side of the window, then select the object it 
will tell you how many nodes are used by it.  It is then a simple matter 
to split (Tools->Split Way) the way into two (or more) pieces.  If its a 
loop way then select two (or more) nodes on opposite sides and then 
split it.

If you do the split after adding all the tags or creating the 
multipolygon they are copied to the new way.
