Recent libc change breaks Solaris 10 Branded Zone Support

This is a brief bug report, but basically after rebooting onto a newer SmartOS image, it is no longer possible to run Solaris 10 branded zones:
root ~ (so1-12.ixlon1): zlogin c1bd276d-291f-4bfc-bae9-0e0e36b9b18e [Connected to zone 'c1bd276d-291f-4bfc-bae9-0e0e36b9b18e' pts/7] Last login: Thu May 16 22:37:40 on pts/10 -bash: cannot make pipe for command substitution: Invalid argument -bash-4.2# logout [Connection to zone 'c1bd276d-291f-4bfc-bae9-0e0e36b9b18e' pts/7 closed] root ~ (so1-12.ixlon1): ps -fz c1bd276d-291f-4bfc-bae9-0e0e36b9b18e UID PID PPID C STIME TTY TIME CMD root 10246 1 0 15:46:22 ? 0:00 /lib/svc/bin/svc.startd root 8976 5720 0 15:46:21 ? 0:00 /sbin/init root 5720 1 0 15:46:18 ? 0:00 zsched root 10367 10246 0 15:46:23 ? 0:00 sulogin root 10436 10367 0 - ? 0:00 <defunct>
Hardly anything is running as a result, the zone effectively hasn't reached multi-user.

I believe this may have been caused by postwait's recent changes, but I'm not clear as I haven't been following illumos development closely lately.
I'm not clear on whether this can be addressed in the Solaris 10 branded zone layer itself.
I can supply access to a development machine if someone wishes to work on this.

Thank you very much for your work on this earlier today, it's greatly appreciated.
We'll test the patch tomorrow and let you know if it works fully.
If it does hopefully this can be webrev'd, reviewed and then RTI'd.

Looks like this fixed pipe, but accept is still broken. inetd fails to start (plus presumably anything else calling accept).
Would you be able to do the same thing for the other libc functions changed recently?
I can test these too.
