No, it doesn't...
$ grep -rF 'I/O possible' gdb-6.3
gdb-6.3/libiberty/strsignal.c: ENTRY(SIGIO, "SIGIO", "I/O possible"),
gdb-6.3/gdb/proc-events.c: { SIGIO, "SIGIO", "Socket I/O possible" }, /*
alias for SIGPOLL */
gdb-6.3/gdb/signals/signals.c: {"SIGIO", "I/O possible"},

I have seen gdb drop out with this message when debugging c, c++ as well as
ruby projects, but not frequently. In this particular example, I immediately
re-ran gdb with the same commands and it worked exactly as expected.
I don't see 'I/O possible' often, but when I do gdb always seems to just exit.
This is running on linux x86_64 64bit linux with recent (-branch) glibc+nptl
