Subject: [Boost-build] question(s) about bjam code

Hi Steven, all,
as I'm getting sucked deeper into the low-level bjam source code, I have
a few questions, notably about the inner workings of the execution state
machine in make1.c
(Please let me know if I should ask these questions offline, or in form
of github issues (which github suggests to create if I click on an
individual line of code in its browser).
Here is my first question:
I'm looking at
and wonder why, despite the inline comment above the referenced line,
this is not the first statement to be executed in the make1a function. I
understand that the make1a function may be called multiple times from
different locations, but should be ignored (i.e., should be a noop) in
all but one case.
However, each time the function is called, its parent's async counter is
incremented (as long as this target 's progress is not yet RUNNING).
Am I missing something ?
