Thank you

The last time I tried to enable the "macho" module by default both Coverity and ASAN found issues that original author never got fixed. For that reason this module is still disabled by default and not documented. I didn't want to encourage people to use it, knowing that it may have security issues. @knightsc did some refactoring long ago, so the first thing I'll do is enable back and see what ASAN finds.

Do you guys have used this module in production? Never had any problem with it?

[nyx0]

I'm using it and I didn't have any issues so far, but I definitely didn't try all methods

I'm interested in this module, thanks for documenting it! interested if other folks are running this in production and why this PR wasn't addressed if it's available?

[HydraDragonAntivirus]

I'm also interested.
