2s is the longest of the (still arbitrary) timeouts in this list:
https://cs.opensource.google/go/go/+/master:src/net/http/serve_test.go;l=5761;drc=21015cf6baed45a1e7c3d1a0dfe34c778140344f

But the test is only setting ts.Config.ReadTimeout — so why is the write operation in the TLS handshake also timing out? 🤔

Change https://go.dev/cl/529755 mentions this issue: net/http: eliminate a goroutine leak in (*persistConn.addTLS)

gopherbot pushed a commit that referenced this issue Sep 20, 2023
In case of a handshake timeout, the goroutine running addTLS
closes the underlying connection, which should unblock the call
to tlsConn.HandshakeContext. However, it didn't then wait for
HandshakeContext to actually return.

I thought this might have something to do with #57602, but as
far as I can tell it does not. Still, it seems best to avoid the leak:
if tracing is enabled we emit a TLSHandshakeDone event, and it seems
misleading to produce that event when the handshake is still in
progress.

For #57602.

@paulzhol, there are a lot of these on the freebsd-arm-paulzhol builder. Maybe something to look into?

The last 3 appear to be almost a month apart from each other on a Friday/Saturday, which is the weekend for me here.
I might be hogging the internet which has been a mobile CNAT for a while now.
I'll try to be more aware to the fact and maybe shut down the builder at those times.
