libssh write problem

[Vasuki Gubbi <gkvasuki@xxxxxxxxx>]

Hello,

I am using libssh 0.5.2 in a multithreaded application. I establish session
and also write simultaneously to multiple different hosts simultaneously.

I have following code to work with pthread library.

ssh_threads_set_callbacks(ssh_threads_get_pthread());
ssh_init();

I am using sockets in blocking mode. But I see once in a while method
struck in channel_write call. I am enclosing the 2 threads that are struck
in this position and does not seem to comeout of it.

Does anyone know if my usage of library is wrong or it is a some kind of
bug in libssh?

Thanks and Regards,
Vasuki
