I'm currently trying to use the API to implement stack unwinding for
OpenJDK. So, I have useful experience to report which I will add asap.
I'll also add some corroborating detail to bugs raised by Tom Tromey as
he was doing his spider monkey implementation.

n.b. Phil Muldoon also opened this tracker bug for things which my
implementation (also Tom's) is currently having to work around:

  https://sourceware.org/bugzilla/show_bug.cgi?id=19923

n.b. despite a few problems I /have/ managed to get a basic unwinder &
frame decorator to work on OpenJDK8 and 9 without needing to modify
OpenJDK to do so. These issues are either limiting its function or
rendering it less than unrobust. It's a great API.

As soon as I can I get my current code into a public repo I'll link it
to the page above.
