I'm unable to reproduce the problem mentioned myself, and code inspection shows no problem for x86_64 at least.

Specifically hw/char/serial.c has a serial_xmit() method which calls qemu_chr_fe_write(), and if it sees EAGAIN, it sets up a event notification to re-try the write later.

Can you provide the full QEMU command line you are using, include the emulator binary.
