Probably because a lot more code is executed in user-space than in
kernel mode.

I have actually tried the current git tree, and it is indeed not working
as I was expecting. Last time I tried, it was working correctly for me,
it seems something has broken MIPS host support in the meanwhile. It was
commit 60bf84cf4ce277e1212929f35674796888a681ce in case you want to try
it.
