Just an update. I don't think that the problem is with curl. I did an
strace on the curl process doing the chunked upload, and it is clear
that it sending variable sized chunks in sizes much larger than 128
bytes. Something else along the way is causing our server to see only
128 byte segments.

Thanks a lot for answering my questions. I appreciate it.
