In general there is no downside. Shared memory is swap-backed
(though the in-kernel control structures are not).
I think it's high time that the system defaults be raised. I'll do
it later today. You should also be able to raise the defaults
using appropriate sysctl's, e.g.:
sysctl -a | fgrep kern.ipc
sysctl -w kern.ipc.shmmax=33554432
And, of course, with kernel conf variables.
