Tried both approaches. Removing LOG and DATA files doesn't
help. venus just recreates them at next launch and still
complains about rds_zap_heap failure. 

I tried to set mapprivate=0 instead of 1, but that only changes
error code from RVM_ENOT_MAPPED to RVM_EINTERNAL and still dies.

Next, I've cleared MAP_FIXED from mmap flags in rvm (I found a 10
years old post that pointed this to be the problem in some
systems). It didn't help either.

Finally I set dontuservm=1 (yes, I know it's dangerous, I just
wanted to see what happens next) in venus.conf.

With that setting I first do:

$ terra-start

and get a lot of output like:

        TERM_PROGRAM Apple_Terminal
Serving Syscalls  on local socket at '/Users/pki/.ulocoda/ullib.socket'
<_MainThread(MainThread, started)> Initializing server thread Library server, serving socket /Users/pki/.ulocoda/ullib.socket, call handler = __main__.Syscallhandler
<ServerThread(Thread-2, initial)>

.....
<ServerThread(Thread-2, started 4313321472)> Running server
Thread-2


Next, in the other terminal I type:

$ venus-forever

and venus appears to finally start:

Date: Mon 02/25/2013

However it seems that something more doesn't work here, because:

$ clog
username: pki_at_otwieracz.localnet
Password: 
Local login only, could not contact venus


$ ls /coda
NOT_REALLY_CODA


codacon appears to connect to venus, and after some time gives
messages like Begin/End DataWalk.

So I think I miss something simple here. Maybe one more program
should be started or some options are missing. It would probably
help if someone who have seen such configuration working could
share his setup, or review above steps.

RVM issue needs probably more time to be resolved, so before
going deeper into it I would like to make sure that it's the only
missing part.
