I'm not aware of a single document that discusses this in particular.
A general description of how signal handlers work can be found in any
(reasonable) Linux kernel book (including the one by yours truly).

The getunwind() system call and the DSO-approach are probably not very
well documented at the moment (the former was a stop-gap solution and
the latter is still quite new in glibc and, AFAIK, not fully
documented yet).  But in any case, applications shouldn't have to
worry about these details when using a proper API, which in the case
of Linux, is libunwind.
