That's more likely a bug in the Solaris cloning code. I'd personally like
to see it have the additional /dev/ptmx interface such as SVR4 has, because
a lot of software can support this now--and it wouldn't require
"scanning" all the pty nodes with open(2) to find one that wasn't in use.
(Look at the code in compat/svr4 that implements the ptmx device emulation.
There's gotta be an easier way than using this kind of code over and over
