Over time your system will still run out of virtual memory and as the
system is pushed into an OOM situation random processes will be killed.
Coda is still trying to fit up to 315MB of data into 186MB of VM, the
difference is that it will only do this over time as pages are getting

Adding swap is really the only reliable way to make sure your server
doesn't die unexpectedly. Although RVM files and map_private=1 are still
very useful, those will greatly reduce startup times because it avoids
the memory/swap trashing behaviour during startup.
