This same error is happening frequently on the android-arm builder since I cleaned out its TMPDIR:

I've been unable to reproduce this. I've also read the code and can't see how it might occur.

There have been a number of fixes recently in the transport code, so hopefully one of those fixes also got this.

Please re-open if you see this again.

This appeared again this morning on linux-386, rev 3ca2021:

http://build.golang.org/log/9787432466e57bea66b3084a69f8a81a10603642

I still have no way to reliably reproduce it.
