para-callgraph.stp - Callgraph Tracing with Arguments
Print a timed per-thread microsecond-timed callgraph, complete with
function parameters and return values. The first parameter names the
function probe points to trace. The optional second parameter names
the probe points for trigger functions, which acts to enable tracing
for only those functions that occur while the current thread is
nested within the trigger.
