Wine uses them for DPMI support, though that would only get used when
vm86 mode is available.

er of users, and we still
regularly get bug reports about specific 16-bit apps. It would be really
nice if we could continue to support them on x86-64, particularly since
Microsoft doesn't ;-)

It could be a mix of both, there are various thunking mechanisms that
allow 32-bit binaries to use 16-bit components. This was pretty common
in the Win95 days.

However, I'm only aware of one application using this, and being able to
catch and emulate sldt ourselves would actually give us a chance to fix
this app in newer Wine versions, so I'm not opposed to having it
segfault.
In fact it would be nice to be able to make sidt/sgdt/etc. segfault
too. I know a new syscall is a pain, but as far as Wine is concerned,
being able to opt out from any emulation would be potentially useful.
