is a debug subchannel in the FE/BE protocol. I'd suggest inventing
a single Debug message type (sendable in both directions) with the
contents being specified by a separate protocol definition. Or perhaps
invert that and imagine the FE/BE protocol as embedded in a debug
protocol.
I think this is a bad idea. PL/Java will use either shared memory or a socket to attach and
as you already mentioned, when using C, a gdb will attach directly using the pid. I wouldn't
be too surprised if Perl, Python, and PHP all have a similar solution and thus have no
benefit from additions to the FE/BE protocol. IMO, debugging should be language specific and
take place in a separate channel. There's no gain whatsoever mixing it with the FE/BE protocol.
