I wonder why qemu-ga is a user-callable binary as installed
by `make install'. It appears to be a system daemon which,
at the very least, requires root privileges to write its
pidfile and open the transport device.
Shouldn't it go to $sbindir or even $libexecdir instead of
the current $bindif ?
Libtool will be used for final link, the rules do nothing if

The Windows event loop cannot be converted entirely to g_poll(3). It
will still need select(2) so add functions that convert between Poller
and rfds/wfds/xfds. This way most code only needs to be aware of Poller
but it will still be possible to invoke select(2).

QEMU currently uses select(2)-style rfds/wfds/xfds for file descriptor
event polling. Unfortunately the underlying fd_set type and its macros
(FD_SET()) have a hardcoded maximum for file descriptors. It is
possible to exceed this limit so we need a more scalable event polling
structure.

Commit eeb6b45d48800e96f67ef2a5c80332557fd45ddb (block: raw-posix image
file reopen) broke the build on OpenIndiana.
illumos has no O_ASYNC. Exclude it from flags to be compared
and instead assert that it is not set where defined.
Cf. e61ab1da7e98357da47c54d8f893b9bd6ff2f7f9 for qemu-ga.

What about using the linux pagemap?
With RDMA, I have exactly this problem. The cost of mapping and faulting
and checking for zeros is higher than the cost of simply dumping the
page into remote memory on the server side.
If we could avoid accessing the page, it was save huge amounts of time.

being checked; don't skip looping over the children.
