Well, an optimistic guess is that it still takes about one year
to get everything done. Moving msdos/int21.c and msdos/dosconf.c
is just the first step. After they have been moved, winedos
DLL will import 20-30 private functions from other DLLs.
Fixing these imports is going to take time. The largest set
of imported private functions is DOS memory management
(which could be moved to winedos, by the way) and file
handling (which should probably be left where it is now).

Also, timer handling (memory/instr.c), IO emulation 
(msdos/ioports.c) and VxD handling (msdos/vxd.c) probably 
need some work. This is not directly related to DLL separation,
but it might have some impact on it.
