AIUI, Asterisk opens for append the Master.csv file, (fopen (... "a")) 
which creates the file if it doesn't existis.. writes a line to it then 
closes it for each CDR recorded, so ...

You can rename the Master.csv file then email the file then delete it...

Pseudocode:

Once every 10 miuntes from cron:

   if Master.csv does not exist, then exit	// No calls

   rename Master.csv work.csv
   sleep 1
   process and email work.csv to whoever
   delete work.csv
   exit

The sleep may not be needed, but it won't do any harm in the event that 
you rename the file after asterisk opens it but before it writes the line 
into and closed it.

And instead of deleting the work.csv you could append it to some other 
file for a permanent log...
