Using mod_wsgi made the problem go away for Firefox.

Limiting my research to an interaction problem between Apache and Safari, I stumbled upon this bug report for Apache https://bugs.webkit.org/show_bug.cgi?id=5760 that describes something very similar to what is happening and it is apparently still open. Reading this gave me the idea to try and disable the keepalive and, though I need to test it more extensively, it seems the problem is gone.

A simple:

BrowserMatch "Safari" nokeepalive

in the Apache configuration did the trick.
