I agree that you don't want grep to ignore pipes and I know about the
find workaround, but I still think the fact that two pipes exist by
default in /etc is a bug:
# ls -ld /etc/*pipe*
prw------- 1 root root 0 May 22 14:17 /etc/initpipe
prw------- 1 root root 0 May 22 18:19 /etc/utmppipe
If you want to find something in your config files on almost any
GNU/Linux distribution or BSD or OSX, you can do this:
grep foo /etc/*
But this hangs on every *Solaris distribution since Solaris 2.6. I'd
call that a bug and an approachability issue. A related bug was closed
in Solaris 9 when this feature was finally documented. I logged bug
6437243 against this in OpenSolaris but it wasn't given a very high
priority.
Unfortunately, I suspect 6437243 is an example of a bug which will be
very difficult to fix without breaking compatibility with something
which relies on those pipes being in /etc. I haven't yet encountered
any Linux distributions which don't have examples of bad design which
would be even more difficult to fix without breaking something.

Depending on what his find did, Chris may have encountered a bug. Find
/ or /etc -exec grep foo {} \; can hang on some versions of Solaris

What you describe is not a bug but inapropriate usage.
It would be a bad idea to let grep ignore pipes.
If you don't like grep to hang on pipes, just use:
find /etc -type f -exec grep foo {} +
