Do you know how I can get the output flushed (actually sent to output file handler) at certain point in processing a template. I understand this won't make sense for some construct (such as WRAPPER), but this is not that kind of construct. Is there anyway to do this? In my search I found that years ago somebody put up a patch for incremental output, but at that time the patch still has a lot of issue.
Please note that I don't need continuous incremental / streaming output (although in my case won't hurt), a manual flush will be adequate.
