As suggested in the libssh2 group, I ran libssh2's sftp.c example. The
libssh2 example works consistently with the MessageWay server, I can
download any file without issue. Curl and libcurl, however,
consistently hang after receiving the data and immediately before the
message "SSH DISCONNECT starts now".

displaying the following:

It appears there several differences between the sftp.c example and
libcurl, such as blocking vs non-blocking. I tried enabling blocking in
libcurl but the behavior was the same. I also tried enabling SO_LINGER
with 0 timeout, to no effect. Please let me know if there is anything
else I can try...this seems to be an issue in libcurl with MessageWay.

Thanks
