  Modified:    sys/i386/linux  imgact_linux.c linux_misc.c
  Log:
  This is an extract of changes from what I am currently running...
  - Optimise the linux a.out loading and uselib system calls so they
    take advantage of some of John's recent interface improvements.
    Basically, this means they make far less map changes than before.
  - Attempt to plug some potentially nasty kernel_map memory leaks..
  - Improve support for QMAGIC libs (I only use QMAGIC (ie: a.out libraries from
    the slackware 3.0 dist) but this depends on other changes to enhance
    the /compat/linux support)
  - uselib goes out through a single exit as part of the resource tracking
    that I did when closing the resource leaks on errors.  This could be
    cleaner than what I did, but making a 30-deep nested if/else was not my
    idea of fun, neither did I want to repeat the same code 30 times over for
    each failure possibility.  I guess this function needs to be split into
    smaller functions to solve this.
  
  I've been running the Linux Netscape-2.0 (with Java) to test this, and apart
  from the long-standing problem with the missing scrollbars, it appears to
  still work as before with ZMAGIC libs (and the leaks)..  However, I've
  been using it with mods for the signal trampoline code for native linux stack
  frames on signals and exterminated the blasted sigreturn printf() problem,
  so I can't be certain that there is not a dependency on something else.
