In article <0539,AA0539@chroma>, Bryan Ford writes
that CloseDevice() should be called from processes only, 
because a DELayed EXPunge may cause DOS's UnLoadSeg() to be
called.

This is not quite a valid conclusion because:
  1.  Libraries/Devices can be expunged by the memory allocater
      when RAM gets short, and CERTAINLY AllocMem() is safe from
      a task.
  2.  Actually, UnLoadSeg() isn't called.  Exec (or actually ramlib)
      frees the SegList itself.  If you look carefully, I don't
      think you will find any EXPLICIT references to UnLoadSeg in
      the docs.  [I hope -- I wasn't able to.]
