Description of problem:
If you sync 2 repos both from the same feed that has distribution, it only syncs the distribution to 1 repo.


Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
1. create repo with a feed which has a distribution
2. create a second repo with same feed as above (use relativepath)
3. sync the first repo
4. while the first repo is syncing run sync on the 2nd repo
  
Actual results:
I tried a 2 f16 repos on which the sync said completed but only one repo had the distribution

I tried it a second time with an f15 repo

[root@pulp-v1-server ~]# pulp-admin repo sync --id f15-new -F
Sync for repository f15-new started
Sync: Finished
1112/2941 new items downloaded
1829/2941 existing items processed

Item Details: 
Tree Files: 6/6
RPMs: 2935/2935

[root@pulp-v1-server ~]# pulp-admin repo sync --id f15 -F
Sync for repository f15 started
Sync: Error
