Bug#1115311: wsjtx: Freezes hours later when left receiving (FT8 and Whisper)

Some further info. I have noticed when I log in after being away and WSJTX appears frozen, it is using 100% processor. If I leave it for a few minutes minutes it eventually recovers. However while frozen like this it stops reporting to PSK reporter.

I have a low power processor: Intel J5040 from 2019 (10W passively cooled mini ITX board). WSJTX usually uses about 7% CPU and jt9 uses about 12-20% when everything is normal.

I usually use the USB audio "alsa_input.usb-Burr-Brown_from_TI_USB_Audio_CODEC-00.iec958-stereo" for the rig, but it also freezes using the pulseaudio default with analogue 3.5mm cable. Freezing also happens when I disable the rig connection and just use a stand alone shortwave radio.

I haven't seen freezes with interactive use, or when it is running in the background and I am using the computer.

Any ideas why CPU is pegged at 100% when I've been away for a while? Perhaps this happens to other people, but with a faster CPU the recovery is quick enough they don't notice.

I haven't seen any audio delays or problems.
The program is just frozen, does not respond to UI elements, it doesn't redraw the window, and doesn't respond to closing it with the window manager X icon, until the window manager (xfce4) offers to kill it. Then I have to kill jt9 otherwise it complains about that being frozen when restarted. That might be a clue, but I've never used jt9.

I'll install the newest version from unstable and see if it persists.
