Since commit 8eb13bbbac ("ui/gtk: vte: fix sending multiple
characeters") it's very easy to lock up QEMU with the gtk ui.
If you configure a guest with a serial device and the guest
doesn't listen on this device, QEMU will lock up after
entering two characters in the serial console.Patch 1/2 is a bug fix for 6.1. Patch 2/2 is a preview for 6.2. If there are no objections, I will resend this patch for the 6.2 development cycle together with changes to ui/console similar to the changes in patch 1/2. This will remove the QEMUFIFO code in ui/console.c.
