Previous patch causes a bug in Qemu if the patch
46764fe09ca2e0f15c0981a672c166ed8cf57e72 ("virtio-serial: fix segfault
on disconnect") is not included in that version of Qemu (patch present in
version 2.10.0).
This crash happens when device is closed during a write operation.
For SPICE character device, spice_server_char_device_wakeup is called
to write data which handles both read and write pending operations.
As we want to close the device but we can't do it inside the handler
without causing a crash, this commit schedules a timer that will close the
guest device outside this callback.
The proper solution would be to patch Qemu but making sure of this is not
so easy, hence this workaround in spice-server.
Code is marked with some comments to remember to remove this
hack in a safe future.

SPICE: Simple Protocol for Independent Computing Environments
=============================================================
SPICE is a remote display system built for virtual environments which
allows you to view a computing 'desktop' environment not only on the
machine where it is running, but from anywhere on the Internet and
from a wide variety of machine architectures.
Installation
------------
The SPICE package uses GNU autotools, so the build install process
follows the standard process documented in the INSTALL file. As a
quick start you can do
./configure --prefix=/usr --sysconfdir=/etc \
--localstatedir=/var --libdir=/usr/lib
make
sudo make install
Or to install into a private user specific location
./configure --prefix=$HOME/spice
make
make install
The following mandatory dependencies are required in order to
build SPICE
Spice protocol >= 0.12.13
Pixman >= 0.17.7
OpenSSL
libjpeg
zlib
The following optional dependencies increase the available
functionality
Cyrus-SASL
libcacard >= 0.1.2 (Smartcard support)
Opus >= 1.0.0 (Opus audio encoding support)
LZ4 (LZ4 compression support)
GStreamer >= 1.0.0
Communication
-------------
To communicate with the development team, or to post patches
there is a technical mailing list:
http://lists.freedesktop.org/mailman/listinfo/spice-devel
There is also a mailing list for new release announcements:
http://lists.freedesktop.org/archives/spice-announce/
To view known bugs, or report new bugs, in SPICE visit
https://bugs.freedesktop.org/describecomponents.cgi?product=Spice
Bugs found when using an OS distribution's binary packages should
be reported to the OS vendors' own bug tracker first.
The latest SPICE code can be found in GIT at:
https://cgit.freedesktop.org/spice/
