@node Uptime Counter
@subsection Uptime Counter

now maintains an ``uptime'' counter, in seconds. It lives

. It can be queried by @i

}
, or
seen in memory maps.

know roughly when a node got stuck, and whether software is still
running when a node is not active on the network. Neither of this even
happens in production, but the tool is useful during development.
