Nothing very interesting...

Describe the bug

When I set a breakpoint in a running session using dlv-dap, the process hangs (assuming it wasn't paused when I set the BP).

When I clear a BP in a paused session using dlv-dap, I thrown into src/runtime/sigqueue.go:168

Eitherway - unable to change BPs in an active debug session. I can change them if I exit the process first, and start a new session.

Steps to reproduce the behavior:

launch a go server
to set a BP on something you know will trigger in a moment / after an action
do that action to trigger that code
nothing will ever happen (the process is frozen)
