Chapter 11 of the ia64 software conventions and runtime architecture
manual should be a good starting point. It's ia64-specific, but the
concepts apply to other platforms as well. The PDF is available at:
 http://developer.intel.com/design/itanium/downloads/24535803s.htm
In particular, Figure 11-2 shows the language specific data area
(LSDA).

Hmmh, the LSDA is associated with a particular code range, so it's not
per thread. I'm not sure the LSDA would buy you much more than a way
to identify a particular frame as being an interpreter frame. If so,
there are probably easier ways to accomplish this.
