Ah, ok. I was (erroneously) assuming that the PCU would simply exit at
the time the connection to osmo-bts drops. This way, it re-spawns and
re-initializes nicely when the BTS is sending the next
PCU_IF_MSG_INFO_IND. However, I may be writing too much Erlang code in
recent days, hence my 'let it exit and re-spawn' attitude ;)

Your patches look fine to me. The new gprs_ns_close() declaration of
course would have to go in a libosmogb header file.
I can try to test it later today.

Harald
