How many jobs can BuildMaster run in parallel?

We're starting to get a few applications in now and finding that at times jobs getting blocked because others are already running.

Is it possible to run more than 2 (seems to be the limit) at any one time?

Product: BuildMaster
Version: 4.6.2

UPDATE: This limitation no longer exists in BuildMaster v5 (OtterScript) Plans.

There is no limit to the number of executions that BuildMaster can run in parallel; however, only a single remote action can run on the same remote server/agent at a time.

This means that, for example, if you create a build of multiple applications at once, and all of them build on the same build server, only one of those applications will be built at a time. You can improve this behavior by using server pools if you'd like if you have multiple build servers you would like to utilize. In exceptional cases, you could install multiple agents on the same machine (on different ports), and put those in a server pool.
