Fear my ASCII art status bar.
"720.77MB" is what I got after clicking the GC indicator. (Before,
it was about 300MB.) There were no command-line messages from DrRacket.
I don't think this is an out-of-memory problem. DrRacket has been
good about asking for more during other simulations, my limit is set
to 1024MB, and I really doubt I'm allocating a 304MB temporary object.
I wrote a small program to print 600000 debug messages, thinking it
was a limit on the number of lines in the REPL, and it ran to
completion.
For full disclosure: I paused and restarted DrRacket from the
command line (fg; ctrl-z; bg) a few times while the simulation was
running, so I could use my laptop unplugged without draining the
battery.
Besides running out of memory, what else could cause a program to
halt with "Interactions disabled", and how can I avoid it?
