    Begin work on a syscall hijacking library which can be LD_PRELOADed
    to convince non-rumped applications to communicate with a rump
    kernel instead of the host kernel.  The precision of what goes
    where is not exactly surgical, but for example when wanting to
    debug a web server's TCP/IP stack interaction, it might be enough.
    When all you have is a hand grenade, all problems look like a ....
    hmm?

    There's still plenty to figure out.  For example, I'm not sure what
    the user interface will be like.  Now it just attempts to hijack
    network communication.  It also needs to sync with symbol renaming
    in libc, and maybe autogenerate the non-schizophrenic wrappers
    where the communication is heading to exactly one destination, lest
    I'll be a mummmy by the time I finish writing them all.  As a fun
    example of a non-non-schizophrenic one, consider poll().

    Work in progress, but I managed to get two non-rumped netcats
    talking to each other or fetching the index from a non-rumped
    thttpd.  telnet works in one direction (i can read the data from
    netcat, but anything i send back is not printed).  bozohttpd uses
    dup2() which i haven't bothered to address yet, etcetc.

    (not hooking this up the build for now)
