Thanks for solving this. The patch works for me.

BIOS boot time with qemu-system-i386 is about 41 s (with my code which lacks thread support and ffi it was 40 s).

With qemu-system-x86_64 it is twice as fast, so it looks like in my last report where I said that the new code had doubled the speed I compared different system emulations.

Update: with Richard's latest tci-next branch which includes the fixed code both qemu-system-x86_64 and qemu-system-i386 require about 20 s user time for the BIOS boot.
