- <c>etop</c> had a hardcoded timeout value of 1 second
- when waiting for data from a remote node. When this
- expired, which could happen for instance if there were
- very many processes on the remote node, etop would exit
- with reason <c>connection_lost</c>. To overcome this
- problem, the timeout is now changed to be the same as the
- update interval, which is configurable.</p>
