It's not clear to me how this change solves the issue.  It's a "read 
timeout" so this means the connection has been established. The client 
will not care if the server has enabled SO_REUSEADDR or whether it 
initially bound to a fixed or ephemeral port.

Is this issue Solaris only? I ask because there is an awkward issue on 
Solaris where the kernel will accept a pending connection when the 
process is at its file descriptor limit. We've seen this periodically, 
esp. with tests that leave connections or files open. An unsuspecting 
tests runs later, establishes a connection but gets timeouts as there 
isn't no code at the application level has accepted the connection.
