Output from update listener causes error messages/db server crash
-----------------------------------------------------------------

                 Key: COUCHDB-20
                 URL: https://issues.apache.org/jira/browse/COUCHDB-20
             Project: CouchDB
          Issue Type: Bug
            Reporter: Noah Slater
            Priority: Minor


What steps will reproduce the problem?

1. Write a program/script that continuously reads its stdin and writes 
something to stdout as stdin line has arrived

2. Register it as a db update listener in couch.ini

[Couch]
...
DbUpdateNotificationProcess=/path/to/daemon

3. Start couchdb. Each time db is updated, the listener program receives 
input and writes back to stdout.

This causes long and obscure error messages in couchdb server concole 
output (not showed here). According to [1], listener is not supposed to 
send anything back.

It is therefore proposed that whatever is received from the listener is 
merely logged in special log file e. g. notifier_log (which may be 
redirected to /dev/null in couch.ini if not needed).
