secure being on by default is dubious

[thomcc]

Safe rust code doesn't need the extra checking (statically known to be memory-safe), and the guard pages it uses can easily cause resource exhaustion to occur very early, which will cause an abort.

I've thought this for a while but figured I'd file an issue at least.

@thomcc I initially thought that safe defaults are best. However, now I tend to agree with you. There are still benefits to using safe mode though, for example the myriad of unsafe code instances found in many libraries.

This should be closed, secure is no longer the default.
