Why is taking so long for 1.0.1 to be released?

On a side note, they clearly jumped the version number to "1.0" way too soon. It is nowhere near production-worthy software (which is implied by a 1.0 release).

Apache procedure requires a 72-hour vote window, which will be closing soon.

As far as 1.0 being production ready, yes the bug is unfortunate, but the fix is 29 characters long. Aside from this unfortunate line of code, I'm 100% certain that CouchDB is production ready. Lots of sites have been running it in production for years without issue. An incomplete list of happy users is here: http://www.couch.io/case-studies

Here's the bug-fix, to give you an idea:

I have to say I also really like the fact that recovery is possible to begin with! Are there any other extant db/data store tools which enjoy the same append only awesomeness (as i understand, append only writes are the only reason this recovery is possible, plus in principle allows pretty awesomely fast writes).

It is a catch 22. Not many things can be said to be production ready until proven over time. There are many people using CouchDB in production today, some of the bigger people are the BBC and Ubuntu. This issue and response is a step along the way of proving it's production usability.

Even though I like CouchDB, I find their slogan "CouchDB, relax" pretty ironic right now!

Why if you read correctly the page :

"As long as you have not compacted since installing 1.0.0 and triggering the bug, this tool can help you avoid any data loss. Because CouchDB has an append-only file format, the tool is able to recover any data written, even if your server has been restarted since then."

I think it's pretty relaxing imo to know your data are still here.

While the bug is catastrophic for a 1.0 release, the team responded very well. They did not try to hide anything, they clearly stated the problem and provide now an intermediate fix.
