I can reproduce this every time on Debian Bullseye if, for example, I
disconnect my computer from the Internet but don't tell KMail to 'Go Offline.'

Two processes seem to eat the CPU, and I don't know what their relation is:
akonadi_ews_res and http_so. Here's a crummy backtrace from when I stopped the
former:

I'll work on getting some better ones, but I'd appreciate tips like what
breakpoints to set. I don't remember which way it was but when debugging, if I
stopped one of the programs, a new process would spawn. That makes it tricky to
pin where the fault lies: akonadi_ews_res or http_so.
