Subject: [PATCH 029/119] plugins/open: Fix for interrupted select

The select syscall can be interrupted for signals like SIGPROF. The IPMI
command sent will still be outstanding but the send_command will return
an error. When the next command is sent it will get the completion for
the previous command and has the tendency to break state of end users.
