Not necessarily.  I understand the term "Heavy-Weight Process" to mean
a Unix process, as distinct from a light-weight process, commonly called
a thread.  Linux threads use the standard process infrastructure, so a
process with (say) four threads would occupy four slots in the process
table, and would have four process ids.  It would not be obvious that
this was one process with four threads, and not four separate "heavy-
weight" proceses.
