That'll be after the change. When I traced upto beginparsing, refcount is 1
(loaded the source form file).

This seems to match my findings. The 4th break where the refcount is
dropping to 1 is unfortunately an incomplete stack trace. Are these all
breakpoints you encountered for loading a single file? Ie. This is the end
of DOOPENEDITORFILE. 
Since you have more success with watchpoints than I have (I just checked: my
gdb version is 7.1 on windows and linux), would you mind tracing into
DoOpenUnknownFile. This is used when opening a unit for the first time. That
is where I got the refcount=2. DoOpenEditorFile is used for files that where
already opened before.
