Release upgrade

[Felix]

Hi,
I have some problem with code upgrade.
Im tying to upgrade the code for uploading files with yaws while im
uploading a file.
My upgrade instruction in the .appup file is
{load_module,my_upload_module}.

The upgrade goes well but it seems like upgrade is done on the
currently running upload module when im doing
release_handler:install_release/1 and thus kills the upload. I
expected that the upgrade would take effect first at newly started
uploads...
Should I give a different upgrade instruction?
