Description of problem:

I am using CURLOPT_HEADERFUNCTION for parsing FTP return codes (messages) while downloading via FTP.
I am specially interested in FTP code 213 which returns size of a downloaded file. Sometimes I know expected size and when this size differ from size that server reports (via the 213 code), then I want to interrupt this download.

The download interruption is done by returning a bad return value from the CURLOPT_HEADERFUNCTION callback. But I've met the problem, that after a bad return value is returned, the CURL hangs for about 60sec (just my estimation, I didn't do exact measurement) before it returns from curl_easy_perform().

My expectation is that curl_easy_perform() return immediately after CURLOPT_HEADERFUNCTION returns the bad return value.

Version-Release number of selected component (if applicable):
curl-7.29.0-9.fc19.x86_64
libcurl-devel-7.29.0-9.fc19.x86_64

How reproducible:
Check the attached reproducer

Actual results:
60sec hang after download is interrupted

Expected results:
no hang

It works! Thank you!
Do you plan to make a build with this patch for F18 and F19 sometimes, or it will be only rawhide stuff?
