I cannot reproduce this, neither with 1.8.5.5 nor with 1.9.0. I am also running
Mac OS X 10.8.5.
Note: I tried this both with you original test.sh, and also with a version were
I replaced the ">" by ">>", as per Jeff's suggestion. It (as predicted) didn't
make any difference).
If this is a race condition, it might be easier to trigger it on slower
hardware. I am running this on a 2012 MBP with 2.3 Ghz i7 and an SSD. What is
your test machine?
Cheers,
Max
