From the point of view of a user this is true. From the programmers point
of view this is not entirely true. If the expanded memory is no longer needed
there is a function in the EMS to close the EMM handle and deallocate the
pages of memory. Also, there is no reason that a single application
could no call the memory handler and get several EMM handles as the need
arises. Releasing them individually when no longer needed. The specification
*suggests* that each application may one request at the beginning of the
program, though this is not a requirement. There is no way to release a
portion or increase the size of memory allocated once the EMM handle has
been gotten.
