comment Write to stderr
Huh, I swear I tested my comment here before making it, but now I'm definitely not getting red syntax errors so I'm not sure what happened. Apologies for misleading comment :)

comment Write to stderr
Unless your /bin/bash is statically linked, it will honour LD_PRELOAD since that is actually handled by the dynamic linker. However, it won't be affected to changes to LD_PRELOAD that are made after it has started. If you start bash with the LD_PRELOAD in place, you would get syntax errors in red.

@Emmanuel I didn't, was a sloppy copy-paste-and-edit from another command in my shell environment.

comment Reverse DNS PTR lookups ocurring on each connection
Actually, it looks to me like you /have/ found the issue. When you connect over 22, SSH is likely doing the dns lookup, you can stop it by adding UseDns no to your sshd config and restarting the daemon. On 80, it looks like your python process is clearly doing the lookup.
