moarvm-remote locks when stepping too fast

[eiselekd]

When stepping and continue pressing return the debug protocol seems to
get out of sync and moar-remote will stop responding, requiring to
restart moar-remote.

It start
nqp-m --debug-port=9999 --debug-suspend -e "my $a := 1;"
and
moar-remote 9999

then I enable debug and do a "step into 1". Then I keep the "Return" pressed.
See
x.txt
At the end moar-remote seems to hang and I need to close moar-remote and restart it.

Can you give a tip where to look if I want to fix this? The asynchronous threading networking
code is quite hard to understand.

Is this still an issue?
