They've always been too small. I find it really easy to hit the limit in
"normal" desktop use - I tend to have a lot of terminals open, and find it
difficult to find some processes that I'm happy to terminate when I do hit
the limit. I've had it in Radar for a while (#3537659) but last I heard there
hadn't been any effort to address it.
Thankfully the Darwin source releases have been very punctual for some time
now (thanks Kevin!) so for each OS update I build a custom kernel with
CHILD_MAX (xnu/bsd/sys/syslimits.h) increased from 100 to 500 and hack in a
"ulimit -u" invocation in /etc/rc or somewhere (there being no login.conf or
the like to be able to set it for login sessions).

Since 10.2 I have included the following at the bottom of /etc/rc.common.
It works, or it has for me.
if [ "${TWEAKS:=-NO-}" = "-YES-" ]; then
ConsoleMessage "Tweaking stack, data, and processes"
sysctl -w kern.maxproc=1024
sysctl -w kern.maxprocperuid=256
ulimit -H -u512
ulimit -u256 -s8192 -d12288
fi
I tried adding it to rc, but the change wouldn't hold. Some late process in
the load sequence would reset it (at least in 10.2).
