   Hi Kevin,
   
   There is no plan to make collector thread-safe in near future, since we
   expect topology developers would handle the concurrent issues if they
   create more threads by their own.
   
   Alternatively, got any thoughts on doing HTTP posts without this?
   We have higher level framework summingbird (
   https://github.com/twitter/summingbird/) providing the feature you want,
   and it achieves this feature by:
   1. Maintain a thread-safe queue to keep the results of http posts request.
   2. Create a bounded thread-pool: each thread will do the actual post
   request and put the results into the thread-safe queue mentioned above.
   3. Add the tick-frequency for the final bolt and bind with actual work on
   the thread-safe result queue. Then the results can be handled in main
   thread.
   
   Hope it helps.
