[Mongrel] "reaper" is not picking up new changes to my application???

Can anyone shed any light on why "reaper" (whilst seemingly working re
restarting my mongrel ruby process) does not pick up changes to my
application?  (e.g. changing a title in a view for example).   It's like the
"mongrel_rails start  etc..." is just restarting the current process but
ignoring the new details re where the new application directory is.   That
is with capistrano the new releases are put in different directories, and
are referenced in the command line options to "mongrel_rails", however it
seems these are being picked up.    I basically have to do a "reaper -a
kill" and then a "nohup script/spin" to get it to recognize the new
application directory.

Here's an example of the scenario when I run reaper, the ruby processes is
restarted, but it doesn't pick up the new directory (i.e. application
