Bear in mind that was just one question of many that we asked. We do offer up a lot of general questions such as "describe some ways that web services can be secured". We get good answers from some candidates, while others answer with responses like "it's handled in the configuration"

What's wrong with hardening apache directives ? Not everyone groks mod_security.

I'm not familiar with writing apps for X, but are you saying that every program that displays a window in X can log all keystrokes including in windows that are not associated with that program?

Well try this:
- Find the id of your window of interest (xwininfo).
- Attach to it with xev -id $id

Now that you know ... Ctrl-Alt-Backspace zaps X.

But the protection is not perfect. Throw random data into a few adjacent blocks the way a head crash does, and if those blocks happen to be structural metadata, think about how extensive the data loss could be. In most cases, e2fsck and repair damage like that. ZFS can't.

True I've wondered this myself lately with btrfs. Ext? has backup copies of the superblock. Which it uses during repair I presume.
There is no reason ZFS shouldn't have redundant copies of the critical structures. How foolproof is ZFS data protection for normal data and structural data ? Can anyone shed light on this ?

Now fsck utilities aren't perfect and can worsen your situation. I myself have been bitten by xfs_repair and e2fsck (ext3 fs) in the past for example.

There is absolutely nothing on my laptop that I fear anyone else reading. Nothing. There are no passwords, no legally protected or privileged information, nada. It's an old, slow Dell that works fine for web browsing and simple games, too old to run anything processor- or memory-intensive like MSwindows.

What about saved/cached web service passwords/session cookies etc ...

I've got a nice reproducible case here--memory-intensive command-line utility dealing with image data, run it once it takes 1.5 minutes, run it a second time, it takes 2.5 minutes. No shared memory or semaphores or anything exotic, just malloc, use memory, free memory, exit.

I concurr that Yosemite isn't a very stable upgrade.
But are you sure your issue is related to virtual memory and not to the CPU clocking itself down because of heat.
