I've looked further.

Here's what happens, on TUI + gdbserver:

(...)
Packet vCont (verbose-resume) is supported
Sending packet: $vCont;c#a8...Ack
Packet received: W00
Sending packet: $g#67...Remote communication error: Software caused
connection abort.
(gdb) c
Continuing.

gdb is sending a g packet after a W.  Something in gdb didn't
realize that the the target already exited.  I'm posting
a patch at gdb-patches with a deeper rationale.

Cheers,
