#199: Endless poll in libssh2_sftp_write
----------------------+-----------------------------------------------------
  Reporter: josusky | Owner:

----------------------+-----------------------------------------------------
 When connection is interrupted in the middle of libssh2_sftp_write (e.g.
 by ifdown) it hangs in syscall poll:
 {{{
 #0 0x00007fb84a385203 in __poll (..., timeout=-1) at
 ../sysdeps/unix/sysv/linux/poll.c:87
 #1 0x00007fb8481c7788 in _libssh2_wait_socket (...) at session.c:585
 #2 0x00007fb8481c9c83 in libssh2_sftp_write (...) at sftp.c:1606
 }}}
 Even if the interface goes up the application does not recover.
 I tested it with 1.2.7 as well as snapshot of 1.2.8.
