Problem: Need to be able to define
the default swapping to put on a new structure independent
of the DST for the monitor.
Diagnosis: As above. By having this, structure swapping space
can be large enough to meet future needs
Solution: Add new parameter, SWDST. This is the number of swapping
pages to allocate on the structure. Is defined in STG as:
NDG SWDST,NDST
and can be overriden in PARAMS

Problem: DUMPER does not incremental save files which
have been renamed but not modified.

the source FDB to the new FDB. These words should not be copied, but
should be zero in every new file.
Solution: Change the rename FDB mask to not copy .FBBK0 to .FBBK4.

Problem:
MONPDL BUGHLTS
Diagnosis: SCHEDULAR STACK TOO SHORT IN CASE WHERE BIG BUFFER CODE
TRIES TO OUTPUT A CHARACTER TO A TERMINAL WHICH IS TLINKED TO A PTY.
CONTROLLING JOBS IS THEN WAKED AND IS MADE RUNNABLE, WHICH USES UP
THE REST OF THE STACK.
Solution:
INCREASE NSKDP FROM 67 TO 100. THIS MUCH INCREASE IS NOT NECESSARY FOR
THIS PROBLEM, BUT A LITTLE EXTRA CAN'T HURT.

Problem:
Slow terminal output, especially on 2020. Unable to run
single line at more than about 4000 baud on 2020.
Diagnosis:
Excessive interrupts; first character is completed
before next one put into buffer, so buffers are
deassigned, etc.
Solution:
Don't start output immediately; queue to be started
at 20 ms scheduler cycle.

Problem: DUMPER loops if it is creating
directories on tape and a non-wild directory is specified.
Diagnosis: RCDIR with RC%STP (step directory) and a non-wild directory
string returns success with the same directory number.
RCDIR should return RC%NMD (no more directories) in this case.
Parallel problem exists with RCUSR monitor call.
Solution: Call wild-card step code if either RC%STP was set in the call
or the string has wild cards in it. Used to be only if string had wild cards.
At GETD10+13 and RCU070+7, add TXNN Q2,RC%STP before TXNE Q1,RC%WLD.
