Maybe not for the 2-frame vs. 3-frame case, though it would still be
good to know the exact circumstances.
But for the Solaris 9 stuff, it crystal clear that this cannot occur on
Solaris 10 and up (no single-threaded case anymore since libthread.so.1
has been folded into libc.so.1). Ok to remove this part?
