[Bro] postprocessing extracted files

I want to use Bro to extract files. After extraction these files will 
undergo some post-processing (e.g. lookup in a db of known files). Can 
I be sure, that a file logged in files.log with its hash has been 
written to disk completely? 

If not, I have two ideas how to solve this:
1) use a temporary filename until the file is completely written (like 
a prefix/postfix). exclude temporary files from post-processing.
2) emit an appropriate signal from Extract::~Extract() after the file 
is closed.

I would be happy to implement a solution.
