Web Workers are now available in Firefox 3.5 and Safari 4 (Chrome will 
follow soon):

However, there are some limitations (mostly due to thread safety) which 
make them seem less appealing for TiddlyWiki:
* code has to be loaded from a JavaScript file
* no access to the DOM

While one could imagine workarounds for both issues - e.g. creating 
temporary files with the respective source code, passing raw HTML or a 
list of objects for wikification - the overhead would probably 
neutralize any advantages.
