map_tasks with cache_serialize enabled doesn't work.

[Carolu5r3X]

Hello. I have a question regarding cache_serialize for tasks running in map_tasks.

When running a map_task from a workflow, with cache and cache_serialize enabled for the task called by map_task,
starting two runs with the same parameters the expected behavior would be that the second run's arraynodes would queue and wait for the first run, but they run in parallel. Is there a limitation on cache_serialize to only work for single tasks?

Thanks in advance!
