dd signal output format parsing

I am trying ee on Linux with dd 8.21 and I received some strange error:

$ python -m ee.main if=/dev/zero of=/dev/null count=1024 bs=512k
Traceback (most recent call last): in 0.01 seconds (5.60KB/sec)
  File "/usr/lib64/python2.7/runpy.py", line 162, in _run_module_as_main
    "__main__", fname, loader, pkg_name)
  File "/usr/lib64/python2.7/runpy.py", line 72, in _run_code
    exec code in run_globals
  File "/tmp/ee/ee/main.py", line 193, in <module>
    main()
  File "/tmp/ee/ee/main.py", line 189, in main
    do_dd(args, bs, insize)
  File "/tmp/ee/ee/main.py", line 130, in do_dd
    (bytes, sec, rate) = parse_status(bytes_tx)
  File "/tmp/ee/ee/main.py", line 144, in parse_status
    bytes = int(a[0])
ValueError: invalid literal for int() with base 10: '1023+1'

So, I printed out the a:

['1023+1', 'records', 'out']

It looks like there is difference between dd on Linux and Mac OS X, I assumed since it's mentioned in README.

From dd(1) on Linux:

Sending a USR1 signal to a running 'dd' process makes it print I/O statistics to standard error and then resume copying.

  $ dd if=/dev/zero of=/dev/null& pid=$!
  $ kill -USR1 $pid; sleep 1; kill $pid

  18335302+0 records in 18335302+0 records out 9387674624 bytes (9.4 GB) copied, 34.6279 seconds, 271 MB/s

Here is I ran the commands in Bash:

$ dd if=/dev/zero of=/dev/null& pid=$!
[1] 7767
$ kill -USR1 $pid; sleep 1; kill $pid
2156552+0 records in
2156552+0 records out
1104154624 bytes (1.1 GB) copied, 1.30992 s, 843 MB/s
[1]+  Terminated              dd if=/dev/zero of=/dev/null

Also there doesn't seem to have m suffix as used in README on Linux:

$ python -m ee.main if=/dev/zero of=/dev/null count=1024 bs=512m
dd: invalid number ‘512m’
$ python -m ee.main if=/dev/zero of=/dev/null count=1024 bs=512M
[runs but thorws the error above
