Intermittent deadlineexceeded exceptions on File.Open with experimental blobstore write api

[tempy]

Hello all,

I'm heavily using the experimental blobstore programmatic write API,
and it seems to work fine. However, right now I'm doing some stress
testing and I'm getting intermittent ApiDeadlineExceeded exceptions
with the message "The API call file.Open() took too long to respond
and was cancelled." (I'm using Java.) However, I'm calling this not
more often than once every 20-30 seconds, within my load test. Are
there any conditions I'm not aware of that could cause these
exceptions, and any recommended practices for avoiding them?

Thanks,
Mike

I have also noticed that we get quite a lot of DeadlineExceededException under stress since last SDK update.
