[ros-dev] Recent horrid slowdown

[Phillip Susi]

Really?  That is really strange.  I'm 98% sure that up until maybe a 
week or two ago, it took me around 20 seconds for the file copy portion 
of setup to complete under qemu with 32 megs of ram and now it takes 
around 90 seconds. 

Has anyone else noticed this or am I just crazy?
