If you cat a large file to the console, your other SCPs (notably\nSSH and shells) get nearly no service.  The ksched backlogs about a\ndozen ksched_ticks during the syscalls, which are O(100ms).  With this\nchange, those other processes get a little more attention.\n\nSigned-off-by: Barret Rhoden \u003cbrho@cs.berkeley.edu\u003e\n",
