    Hello BLCR folks,

I have an application which uses tcp, but which I will need
to have work with BLCR.

I plan to use the thread-based callback approach for handling
the network issues.

I have a question about the behavior of select function across
a checkpoint/restart however.  By the time the application
will be able to checkpoint, the only fd's in the select fd
sets will be pipes connected to child processes.

When the checkpointed application is restarted, will the
process return from select with errno set to EINTR?  or will
it continue to be parked in the kernel in the select call?

Thanks for any help,

Howard
