Multipe continous jobs do not follow cron

Problem/Motivation

Hi,

When adding multiple continous jobs, only maybe 1-2 will be processed during the 1st and 2nd cron run.
The rest wont be never processed.

1. Select taxonomy term as a source
2.Select english to source language
3. select correct vocabulary
4. Select target language to "any"
5. click search
6. select all (click the check box over the 1st row in the results)
7. In the checkout select source language again "english" and target language "all" and click Rrequest translation
8. From the configure provider select the correct provider
9. select the "submit all 7 translation jobs with the same settings (I have 7 languages)
10. select submit to provider and continue

Result: Some will be processed, and in the next cron run also. But after that nothing.
So 90% will be left in pending state, and some only to translated.
