There are earlier selects on fd2 that aren't followed by a write.  The 
real problem is the select on fd1 (stdout) that tells you that a write 
would block.

I don't think it would help.  The question is, why can't you write to 
stdout?  It should be connected to sshd which should be passing stuff to 
the invoking ssh and perl should be consuming it.
