It's possible. I suppose it also depends on (a) how much memory they 
think they'll have in machines by the time it's actually a production 
OS, and (b) what markets they're targetting.

Certainly for general desktop or server systems, you might have dozens 
of non-trivial applications running at once. In contrast, I think the 
first target environment for Singularity is something akin to TiVo, or 
Media Center, where you really don't have someone with dozens of windows 
open at once.

But sure, I can see the system evolving to put something like the 
native-code regexp library in a dedicated page of address space, loading 
it on demand, and sharing it with all the different programs that use 
that library. Or, you could just have a "regexp server" where you send 
the strings you want parsed and it returns you the results. This 
wouldn't have a whole lot more overhead than simply calling it directly, 
since you're sharing address space with the regexp server itself. It's 
not like it would have the IPC overhead it would in Windows or Linux or 
something.
