I have modify B18 to use shared memory for a number of data stuct.

I have made major changes to the fhandler code and the proc table
to go to unix style fd system. That mean that no copying is done on
fork for the fd table.

I have also made a number of changes to allocate things on the fly since

I have a share area of memory that is at the same address in each
process.

I have also added a BSD style tty driver to B18 code and now have both
the serial ports and console port using it.  It should be able to handle
other
devices like ptys.  It support al l the standard ioctl for termios.  It
is  done
as ioctl and not differnet call entry points like to current tty driver.

I would be glad to make a tar file of my current  winsup  to allow
others
to see direction I am moving in.  The tar that exits now compile under
B18
but I have a version that works under B19 tree.

The above code has only be run under Windows 95 as I do not have an
NT system.
