I get:
	FAIL: gdb.tui/tui-nl-filtered-output.exp: set pagination on (timeout)
	FAIL: gdb.tui/tui-nl-filtered-output.exp: set height 2000 (timeout)
But I have no idea why.

Although only during run by my testsuite tool:
	http://git.jankratochvil.net/?p=nethome.git;f=bin/hammock
So it may be also because I run the testsuite somehow wrong.

Attaching xz-ed gdb.log.
