Description
Waiting for I/O is an important status for tools, particularly profiling and
monitoring tools, to be aware of.  

Adding this status brings the JVMTI spec and the M&M spec into sync on
thread status.

Adding this new status will require reassignment of one or more existing
thread status constant values.
Comments
EVALUATION I/O occurs at many levels of the Java platform, not all of which can be captured. It is thus not possible to reliably return this status.
