	Probably the best thing for AmigaDos right now would be a sector
cache, implimented at the trackdisk level (or something like that)... You
simply cannot make assumptions about the file system in a volitile system like
this.  The sector cache, of course, would not exist for the ram disk.

	The Amiga is notorious for not being nice to the poor user when it runs
out of memory.  I suggest another call be added that the system can make on
devices, etc.... requesting them to get rid of any data they don't need (e.g.
like a cache) because the system is running out of memory.  For instance:

	The disk-driver can flush it's cache (when it gets one)
	The serial device can decrease the size of it's buffer
	Inuition can do lot's of neat things... like disallow window moves AND
		deallocate memory used for the purpose of window moves (I'm 
		just guessing here)

	Most importantly, the system should return 'Fails' to user processes 
which request memory when there is less than, say, 10% memory left (that way,
the system isn't likely to run out of memory at a critical time)
