Checking this with:

```
$ echo 'Content-Length: 51\r\n\r\n{"command":"disconnect","seq": 1,"type": "request"' > /tmp/partial_message
$ lldb lldb-dap
(lldb) process handle -s true SIGPIPE
(lldb) process launch -i /tmp/partial_message
```

Without the `LLDBDAP_LOG` env set is how I found the crash and the SIGPIPE write error. It was from logging here https://github.com/llvm/llvm-project/blob/12c5a46c300eedb6cafc68b987abb9c1fa913e96/lldb/tools/lldb-dap/lldb-dap.cpp#L596
