[lldb-dev] C++ API: Passing information from debuggee to debugger

I need the deguggee to stop and pass some information to the debugger - if the debugger is attached, that is. And I want to do it from different threads in concurrent manner. So, I thought maybe I use run-time signals on Linux: i.e. the thread would:
Fill out some buffer with data the debugger needs to seeSend signal 35 to itself passing the address of the buffer as a payload:
sigval value;value.sival_ptr = address;sigqueue(gettid(), 35, value);
In the signal handler just ignore the signal
If debugger is attached, it will see the signal and inspect info->si_value.sival_ptr. But unfortunately LLDB reports only signal number and drops the value on the floor.
So, is there any other "legal" way to achieve what I need?
