Unhappy to report - this is not a consistent solution :(
Sometimes it works; other times, I can call inet_db:start/0, wait for a
process with the name inet_db to be registered, and sleep for a whole
extra second - and the problem is still there - all calls to
gen_tcp:accept/1 immediately return {error, closed}.
It is possibly a FreeBSD thing - I'm running 4.5-stable and "stable" can
be something of a euphemism in FreeBSDtalk :)
So, back to echo 'myapp:start().' | erl, for now...
