>Description:
	I run a dovecot IMAP server on my machine.  When I connect to
	it from Emacs, the imap process goes to state "tstile" and
	Emacs to "pipe".  Emacs does redraw itself, but can't be
	cancelled.  More and more processes get stuck in state
	"tstile", and I can't open a new terminal.  When I zap X and
	type "sudo shutdown -r now", the shell gets wedged too.

	I downgraded the kernel sources to 2007-03-12, and the problem
	no longer happens.
