This issue affects many JITs. The WebKit JIT is affected too. Actually, the
execmem boolean has been enabled by default for a while, did it get disabled
again in F17? We had been disabling the QtWebKit JIT, but we reenabled it
when we found out execmem got enabled by default. More and more things in
Fedora use JITs (see also Orc etc.), and those JITs all tend to require
execmem, with upstreams showing little to no interest in changing them not
to. (There is a way, but 1. it's complicated and 2. it hurts performance.)
