EMM386 seems to be a problem for both v1 and v2.  The FAQ mentions that
the DOS 5 version may not work at all (with 1.x).  I find:

1. EMM386 with RAM and NOEMS options seems to work
2. EMM386 with RAM option corrupts something such that a spawn from a 1.x
   program crashes on return if the program uses enough memory that swapping
   is necessary.  Same program modified for djgpp v2 seems not to crash.
3. EMM386 with no amount memory specified in config.sys defaults to 256K.
   Both v1 and v2 use only this amount of memory before swapping.

Number 3 is worrisome because it seems to apply to v2.  I know enough not to
set up emm386 this way, but other people who use my software don't.  I really
hesitate to tell people to fiddle with their emm386 setup because it's very
easy to break some other program, or to end up with an unbootable
configuration.  Is there any way to tell v2 what type of memory to use?
