Confirmed (on a circa 1500 line xml file: spinning ball for about 30  
seconds for a regex replace of "\n" with ''). Seems to be somehow  
tied in with the fact that we're searching for "\n", as any other  
search, even with regex turned on, seems to be at least an order of  
magnitude quicker. For instance, I searched for "a" and replaced it  
with "<??>" (ie something unlikely to occur in the file) with regex  
turned on, and the query has four times as many matches and returns  
in a couple of seconds.

Would you believe "TextMate"?

Text => Filter through command... => (Input: Document, Output:  
Replace Selection)

perl -pe 's/\n//g'

Pretty much instant. Undo is also virtually instant, should you not  
like what it's done to your document! While the "g" isn't strictly  
necessary in this instance it is in general if you're wanting to  
replace all occurrences.

For more generic regex substitutions just throw your "Find" and  
"Replace" regexes between the leaning matchsticks. For case  
insensitive matching you can use

perl -pe 's/\n//gi'

instead. Not ideal, but infinitely faster than the builtin (for now).
