to clients that don't send an ident and add a TODO item for 6.2 to
make ident timeout time configurable in the ircd.conf.
Currently it's only configurable in the include/defaults.h (ugly)
or on-the-fly with /set (doesn't persist, have to re-set it on each
restart/server).
they are ALL gone. all of this stuff is now determined at runtime via getrlimit(2).
- due to this, devpoll is broken. i'm not motivated to fix it at the moment.
