This isn't a bug, but do the two block comments here add anything over
the code they sit above? The first sits above settimeo(fd,
connect_timeout_ms) where connect_timeout_ms was computed with MAX(...,
CONNECT_MIN_TIMEOUT_MS) on the line before. The second transliterates
the condition on the line below (timeout_ms != connect_timeout_ms means
"restore it"). Could they be trimmed to a single line about why a larger
connect budget is needed?

                            ^^^^

This isn't a bug, but could this call fit on one line? With the leading
tab it comes to about 71 columns as a single statement, well inside the
80-column limit. Elsewhere the file only wraps arguments when the line
doesn't fit.
