There was a regression reported by Eric Auger before with OOB:
http://lists.gnu.org/archive/html/qemu-devel/2018-03/msg06231.html
The fix is 951702f39c ("monitor: bind dispatch bh to iohandler context",
2018-04-10), which is in master already.
For the bug, we turned Out-Of-Band feature of monitors off for 2.12
release. Now we turn that on again after the 2.12 release.
This patch partly reverts be933ffc23 (monitor: new parameter "x-oob"),
meanwhile turn it on again by default for non-MUX QMPs.
