This is not causing a problem or bug, but is none the less not
correct - as you know, packet_write_gently() takes a 'printf' like
variable argument list. (So, buf.buf is the format specifier and
buf.len is an unused arg).
I think I would write this as:
strbuf_addf(&buf, "poke %d", getpid());
if (requested_capabilities && *requested_capabilities)
strbuf_addf(&buf, " %s", requested_capabilities);
if (packet_write_gently(fd, "%s", buf.buf))
... or something similar. [Note, just typing into my email client, so
it's not been close to a compiler.]

Why are you sending a flush packet - doesn't the index-helper
simply ignore it?
I haven't tried this yet BTW, just reading patches as they float
on past... ;-)
