I implemented a "max content length = xxx" flag, which defaults to 10MB. If an
attachment is larger, an error gets displayed. The problem is that elogd can
only send the error message to the browser *after* it received the whole
request, so it has to "drain" the 240 MB first, which could take quite some
time on a slow connection.

Alternatively, I can cut the connection to the browser immediately, since the
HTTP header contains the content length after the first ~500 bytes, but in
that case the browser only shows a message box "Document contains no data"
which gives the user noe clue of what's wrong.

Anyhow the biggest problem of elog in high stress environments is that it's
single threaded. So if someone issues a search in a large logbook, it could
take some time, in which elog cannot respond to other requests. Maybe I will
find time in the future to make elog multithreaded, but certainly not in the
near future.
