Bigcouch restarts on PUTs to update handler with bodies larger than a determined size.

On a test machine, I create a file at @/tmp/body.json@ containing a 23 Mb body, and then do:

#!/bin/sh

HOST=127.0.0.1
PORT=5984

DB=test-db
DOC=_design/docs/_update/put/largedoc

curl -X POST \
    -d @/tmp/body.json \
    -H "Content-Type: application/json" \
    http://@${HOST}:${PORT}/${DB}/${DOC}

This causes the server to restart:

Note: bodies smaller than 23 Mb do not cause the server to restart.

The bigcouch lead developer has commented on this problem:

16:05  the only other thing would be couchjs's stack size, which is not configurable in bigcouch afaik (though it is in recent couchdb's), but it wouldn't crash beam.
