Out of curiosity, is it harder or you just didn't try?  It would be nice
if the commit message mentioned the problems (if any) in addition to the
reason why you didn't do it.

Having similar policies for user and softmmu emulation is much more
maintainable (for an earlier example, see the unification of user mode
emulation's start/end_exclusive logic with softmmu's "safe work").
