[R-SIG-Mac] source() hangs on import

[Don McKenzie]

Yes. Duh.  Overthinking the "reproducible" part and responding too  
quickly.  Here's one that produces the behavior.

myfile <- data.frame(x1=runif(100000),x2=runif(100000),x3=runif(100000))
dump("myfile",file="myfileR")
source("myfileR")

The source() part takes ~10 sec. in R 2.9.2 on my old powermac, but  
hangs in 3.0.0.
