It would be about memory reads.

Sorry, the phrase "(e.g.  shared library files)" was misleading.  In our (Intel)
downstream debugger, in-memory solib files are JIT'ed and are accessed via the 'm'
package.  That was the background why I wrote "e.g. shared library files".  I will
remove that phrase in the next version to avoid confusion.

Thanks.
