The point is that time slicing behavior is system dependent.  For
example, GNAT on Solaris maps tasks to threads and they will behave as
you were expecting (switching context for IO, etc.).  I believe that
GNAT for Linux will do this too (I think the P-threads impl to which
tasks are mapped on Linux are "real" threads in this sense - but I'm
not sure).  Actually, GNAT running on anything with native threads
will probably work this way.  For example, GNAT for Win95 and NT maps
tasks to Win95 and NT threads and this should again give you what you
expect.  Actually, that brings up another point.  Since you have Win95
why are you running the DOS version of GNAT under a DOS window instead
of just using the native Win95?
