Thanks for the patch. It works in as much as libssh2_sftp_read with a 6MB buffer no longer blocks on the first attempt. The first read is very quickly successful. However, subsequent reads are very slow. They cause 100% CPU usage and the teeny script, based on the standard example code with a 6MB buffer, uses 50-75 MB of memory. >From watching the network meter, it seems that the 6MBs of data is transferred in a fraction of a second but that libssh2 spends the rest of the time reassembling it before returning from libssh2_sftp_read.
