Comment (by starlight):
Have been seeing the problem where the guard relationship
is stable and and good, but where new circuits are
established. Possilby new TCP channel connections
are created due to inactivity time-out of previous
channels and/or possibly it was due to
{{{

different places. Giving up.
}}}
This seems a serious bug. Might be possible to use the
behavior to deanomize traffic.
The attached graph shows what happened when two
RVAL=$RANDOM curl --socks5-hostnam -U $RVAL:$RVAL
hXXp://<ip_addr>/<file_path> &
commands were started within a few seconds of each other.
