Hmm.  I suspect the reason for ucontext.h was that that's the API exposed
by Solaris and other platforms with those context management primitives.
On Solaris, /usr/include/ucontext.h defines the userland API, and does a
nested include of /usr/include/sys/ucontext.h for some of the structures,
and the APIs for the system calls.
