creating size-limited tar files

Simple problem, given a lot of data in many files/directories, I
should create a tar file splitted in chunks <= a given size.
The simplest way would be to compress the whole thing and then split.
At the moment the actual script which I'm replacing is doing a
"system('split..')", which is not that great, so I would like to do it
So I thought about (in pseudocode)
if size(tar_file) >= limit:
tar_file = new_tar_file()
which might work maybe, but how do I get the current size? There
should be tarinfo.size but it doesn't exist on a TarFile opened in
write mode, so should I do a stat after each flush?
Any other better ideas otherwise?
