Try rewording stuff talking about unwinding. Hopefully it will make llvm sound less bad, and still make John happy. :)

better interoperability with external source bases, a new example language
front-end, and improvements in a few optimizations.</p>
<p>At this time, LLVM is known to correctly compile the C &amp; C++ SPEC CPU2000
benchmarks with the C backend (X86 only), the Olden benchmarks, and the Ptrdist
benchmarks. It has also been used to compile
<b>many</b> other programs. LLVM now also works with a broad variety of
C++ programs, though it has still received much less testing than the C
front-end.

Note that the Sparc and X86 backends do not currently support exception throwing
or long jumping (including 253.perlbmk in SPEC). For these programs, you must
use the C backend. Support for unwinding will be added in a future release.
The LLVM native code generators are very stable, but do not currently support
unwinding (exception throwing or <tt>longjmp</tt>ing), which prevent them from
working with programs like the <tt>253.perlbmk</tt> in SPEC CPU2000. The C
backend and the rest of LLVM does support these programs however, so you can
still use LLVM with them. Support for unwinding will be added in a future
release.
