If I execute this in a workspace, I get an infinite loop. I think it's a 
problem with the expression - don't ^\s* and \w+ look for the same 
thing? Anyway, wouldn't '\w+|\s+' do what you want?

'this is a test' allRegexMatches: '\w+|\s+'
	"=> ('this' ' ' 'is' ' ' 'a' ' ' 'test')"

Or if you just want the words, '\w+'. And, if you just want the words 
then you can probably just use #findTokens:

'this is a test' findTokens: ' '
	"=> ('this' 'is' 'a' 'test')"
