Delete original input file after delayed_paperclip processing

Hello all,

I am downloading a file from S3 for processing with paperclip and
delayed_paperclip. The original downloaded temp file is remaining after
processing completes. I'm pretty sure I could add the code to remove
this file in the after_post_processing method.

However, since the process gets handed over to delayed_paperclip, I do
not know how to access the pathname of the original file once processing
is complete? Is paperclip storing the pathname in a property somewhere?
