There is one irritating thing about the new DA scheme in system 7.0.
You can no longer open a DA within the application heap.  Frequently,
I run my FOP postscript interpreter, which requires me to operate the
chooser to switch between the laserwriter and deskwriter printer
driver.  FOP, the FOP spooler, System 7.0, and MS-Word, take all 5Mb
of my memory.

It is very irritating to be unable to open the chooser because you're
low on memory.  Sometimes you get to a critical section in your work
and you want to print.  Leaving your application might destroy the
object you want to print.  The chooser has no memory so you end up
deadlocked, unable to choose -- unable to print.  This was never a
problem before. Some life-critical DAs should be able to run in the
system heap, using some sort of memory emergency-reservation scheme.
