Comment (by sa2ajj):

 "brson" said in a Rust related [https://github.com/rust-
 lang/rust/issues/19079#issuecomment-64028925 ticket] that when they run
 only one build on their EC2 instance, the problem does not manifest.

 So it looks like we might have a problem with temporary names, but I
 really do not know how to approach it.
