FIXME need release of blocks

[eichert12]

There are various places in the code where blocks are used where we have comments that say "FIXME need release...."

block = rb_retain(block); // FIXME need release...

What is the fix for this? What implication does this not being fixed have?

@Watson1978 can you provide any guidance?

[Watson1978]

rb_retain(block) retains the block object.
The object will be used later when block method will be called by some event.
So, we have to keep the block object by using rb_retain(block) which will call [block retain]; in Objective-C land.

If rb_retain(block) causes increasing memory usage, we have to release the object by rb_release().
