[Swift-devel] some racelike condition on file stagein

[Ben Clifford]

I see errors like the below sometimes on my laptop and on the NMI test 
systems, happening in file stagein. It happens sporadically and seemingly 
not very often if at all on i386 linux, so feels like some kind of race 
condition. Every time I've seen it, its been creating a file under a 
non-trivial directory structure (eg under _concurrent) so maybe there's 
something funny going on there.

Its come to my attention because I put in a test that turns off execution 
retries and runs all the local behaviour tests, on the basis that local 
execution should be very unlikely to need retries.


	org.globus.cog.abstraction.impl.file.FileResourceException: Failed 
to create directory: 
_concurrent/aligned-a0f7b757-142a-4c66-8288-bd06ec2d591c--array//elt-4.-field

I'll put some more details in the bugzilla.
