CVS commit: src/sys/netinet

Module Name:    src
Committed By:   dyoung
Date:           Fri Jun  3 20:01:00 UTC 2011

Modified Files:
        src/sys/netinet: tcp_vtw.c

Log Message:
Don't sleep until memory becomes available.

Use kmem_zalloc() instead of kmem_alloc() + bzero().

During initialization, try to get all of the memory we need for the
vestigial time-wait structures before we set any of the structures up,
and if any single allocation fails, release all of the memory.

This should help low-memory hosts.  A much better fix postpones
allocating any memory until vtw is enabled through the sysctl.
