I'd rather not see comments like this added. If it is worth testing..
make a patch and add the test. Especially if the result could be a
segfault. In general, I object to sprinkling checks unnecessarily.. can
SourceNet ever be null at this point?

An assert() might make the assumption clear, a test avoids fixes the
problem (or is overly paranoid), but the comment adds nothing useful.


As a style point, if one "must" add such comments, prefix with "FIXME: "
or "XXX:", as these are picked up by many editors, and can easily be
searched for if anyone is in the mood to review such things.

Generally, I tend to prefer not to see people's names added to comments
in the code. It might put people off editing things if they think a
particular piece of code "belongs" to someone.

git log / git blame etc.. provide powerful tools to investigate the
origin of code lines - if people need to know.
