I.e. about 221Mb virtual and 3.7MB resident.

I have no explanation for my high VM use unless it indicates that there has
been no need for a VM garbage collection since I last re-booted. I'll have
to check the value after I next reboot the PC.
I also tried restarting ctwm on the PC, using
ctwm --replace &
Before and after values hardly changed except for 2MB extra main memory:
Before replace
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
axs 1617 0.0 0.0 221224 3644 ? S Dec08 1:02 ctwm -W
after replace
axs 32155 1.0 0.0 221052 5640 pts/7 S 22:39 0:00 ctwm
So the amount of physical memory has gone up after replace.
I have 8GBram and about 16GB swap (probably a lot more than necessary?)
On a laptop:
I've also tried on a recently rebooted Stonebook mini laptop running
Fedora 31 with 8GB SDram and 16GB swap space.
After exiting ctwm and restarting, on the Stonebook I get this, with
ctwm 4.0.3-post
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
axs 43515 0.1 0.0 219380 5400 ? S 00:37 0:00 ctwm -W
So the large VSZ can't be do to ctwm running for a long time.
There's a lot less running on the Stonebook.
It's mystifying.
