#2254 Binary monitor not responding

[neilsf]

TLDR; VICE with Binary Monitor enabled hangs when emulation is paused

Steps to reproduce:

1. Launch VICE with binary monitor enabled: x64sc -binarymonitor -binarymonitoraddress 127.0.0.1:6502
2. Connect to the monitor and set up a breakpoint
3. When breakpoint fires, wait a few seconds
4. An error message is displayed (see attached image)
5. Redo step 3, but this time send a continue command before the message is displayed: notice the program resumes normally.

Expecting: no error message, program can be resumed any time by sending the continue command.

Using version 3.10r46219 (GTK)
OS: Elementary Linux, (x86_64)

could you test if the same happens in the SDL port?

[neilsf]

No, it does not. SDL port works as expected.

sigh so probably another threading related problem. @dqh will have to take a look
