Is that necessarily a problem?  You have to compile with a 
thread-capable libc and take some
care that the heap implementation is well tuned, but there's no reason 
why the mono housekeeping
threads should cause you any problem is there?  It should be much like 
the embedded Java.

Given that one would want to embed to have very low latency both on 
trigger invocation and
on calls back into the data engine, I don't really see the point personally.

I'm not sure how important it is to make the embeded interface look like 
a standard
interface (in that way that the embedded CLR in MSSQL does - mostly) or 
whether
it can be a thin wrapper over the C API.  I think there's good mileage 
in starting
with the thin wrapper, then at least some common business logic code can 
be used.
