Hi Gerd,

can you (or anyone familiar with those bits) comment on pthread_yield()
in ioport_write() of hw/qxl.c? Which threads are supposed to run this
way? Can't this relation be expressed explicitly? If not, can we use a
sleep here (how long?)?

The background is that yielding easily breaks into pieces when leaving
the SCHED_OTHER space (what we are working on).
