bgpd and lost networks after reload ?

[Peter Galbavy <peter_(_dot_)_galbavy_(_at_)_knowtion_(_dot_)_net>]

I have set up a very basic test network to reproduce an issue I was 
seeing on the weekend.

I have two bgpd's, config files appended. Both running sort of -current, 
one amd64 and another i386.

The behaviour is this:

# bgpctl network sh
flags: S = Static
flags destination
*S    213.253.23.112/28
# bgpctl reload
reload request sent.
# bgpctl network sh
flags: S = Static
flags destination
#


Where did my networks go ? After a reload, local networks get withdrawn. 
I will start to read code shortly.
