Right. But the only increment the API allows to ask for are one whole
bucket's worth at a time.

The filters should be able to handle this. Like I said before, if you
want 10 bytes, fine... just do this:
if (apr_bucket_split(b, 10) == APR_ENOTIMPL) {
/* bucket cannot be split natively */
apr_bucket_read(b,str,&len,APR_BLOCK_READ); /* check for errors */
apr_bucket_split(b, 10); /* check for errors */
}
apr_bucket_read(b,str,&len,block); /* check for errors */
I guarantee you len will come back as 10 every time, because b is now 10
bytes and b->next is all the rest.
[I still wish we allowed pipe and socket buckets to be split natively. I
know Ryan has strongly opposed that idea in the past, but I still think
it should be possible.]
