If you try and create a class during a long build you will eventually get
blocked by the indexer with little feedback to the user except a blocked job
dialog with no info.

STEPS
1) Load all of the SDK into you workbench
2) Create a project unrelated to any of them
3) Start the build
4) Try to create a class
5) You will be blocked by the build
6) Cancel the build job
7) You will still be blocked but you will not know why

I profiled while I did this and discovered that the indexer was taking a lot of
the time - I expect this was because workspace locks were being used locking out
the whole workspace (my class was unrelated to those being built).

I will attach a trace

We could play with indexer thread priority change. When building lower it, and
put it back up at the end. When search query starts in parallel, it is pumped up.

I cannot reproduce this.

As soon as I cancel the build job, my class is created even though the indexer 
is busy.

Tod, if you can reproduce, please attach a stack dump from when you're blocked.
