Certainly.  The nesting level is a per-thread counter.  It is
incremented on a probed function entry and decremented upon its
return.  It is used as an additional index to saved function
parameters by.  This way, if a recursive function is encountered, we
can find the innermost parameters without losing the outer ones.
