Pay attention to the fact that the dovecot daemon dynamically starts the 
imap and pop server executables whenever inboud connexions are requested.

If you upgrade without stopping the master dovecot, and clients request 
connexions, dovecot will try to run the new imap and pop executables, 
which are not the same version as the master, and problems may arise.

The "good" solution is to stop the master dovecot *before* make install, 
and restart it afterwards; or to make sure no clients try to connect 
before you completed the upgrade process.
