sftp_aio_wait_read() and SSH_AGAIN

[Edrusb]

Hi all,

is there a way to have a call to sftp_aio_wait_read() that never return 
SSH_AGAIN, but instead waits until the expected data is ready and then 
return it?

Or, asked another way: when sftp_aio_wait_read() returns SSH_AGAIN, can 
a program call it again right away as there is no chance it returns 
again SSH_AGAIN and thus there is no need to wait/sleep for some time 
between calls in that context, to avoid wasting CPU cycles and creating 
unnecessary load on the system?

I take the opportunity of this question to thank you for libssh, its API 
(which is very easy to use) and the very clear documentation it has :)
