The reason I considered such feature is because I was thinking about whether
a user-level mechanism to build a software DSM (distributed shared memory)
using Java is possble. In such case the user-level add-on program (as a
library) should be able to bring in a copy of "foo" from another machine in
case it does not have one (or if it's own copy is dirty). For such purpose,
the use of user-level SIGSEGV handler has been widely used in many Linux + C
/ C++ DSM implementations. But I believe Java implementations of DSM (such
as Jackal) are mostly in the level of modifying the Virtual Machine in order
to achieve this purpose.

Please, please, please, please, please, please, please do not top-post.
Doesn't anyone any more read the FAQ post that is put up here every five days?

When programming in Java, do not think in terms of machine-level constructs
like SIGSEGV. Think in terms of the algorithms. Java has the facility to
provide the features (goals) you want, but likely not via the techniques
(strategies) you seem to be planning.

Consider grid-computing products like WebSphere's Object Grid for examples of
how others have approached similar requirements.
