As Frank mentioned, libelf already has a DWARF library: libdw.  This is
not the same as SGI's library.  The latter is unusable since the memory
handling cannot be done without leaking.

The header for libdw is not yet installed since I didn't want to expose
the interface until this is needed.  I can do this anytime, though.  And
as far as higher-level functionality which is needed: just let me know
what is needed.  Describe the problems to solve and I can add
appropriate functionality to the library.

/proc seems like the wrong place for many things.  But there are a
number of other filesystems available.  There are special filesystems
for high-bandwidth kernel<->userland transfer etc.  And it is not hard
to write a new filesystem.

The problem with netlink is that the messages which can be read
atomically are limited in size and they are broadcasted.  The latter
would basically mean no sensitive data can be transfered (unlikely) or
the system is unsafe the second you start using this functionality.
