=begin
I have installed the binary distribution of Ruby 1.9.1 for Windows XP and tried to run rdoc on the source snapshot from today as follows:

rdoc lib ext -o rdoc -S -T kilmer

After quite a while this fails with "NoMemorError", see copied output below. My PC has 4GB of RAM installed. The same command has completed successfully on the same machine with Ubuntu Linux 9.04 64 Bit Edition.

Output:

I forgot to note: I tried to run this on my desktop machine because rdoc ext lib never completes on my MacBook with 2GB RAM. I think after a while it starts swapping so much that it slows to a crawl.

As a note, when I run rdoc [v2.3] against trunk on a linux box of mine, it takes up ~1.2 G memory (that's what top shows, so possibly more) then does complete about 10 minutes later. Also with some gems it also uses up all available memory for some reason.

I recommend upgrading to a newer version of RDoc for 1.9.1:

gem install rdoc

Fixing this in 1.9.1 is too hard.
