But in a function there is no scope, so no variable is accessible.
The use case for me is the jstack() function, that would benefit from having
access to some of the globals in libjvm.so. Currently we have a probe on vm_init
to collect those globals and store them for later use in the function. But that
is somewhat limiting the use of the jstack() function (it can only be used after
some probe in the libjvm.so context has been fired first).
