Bug#233933: mouse delays on start

[Glenn Maynard <glenn@zewt.org>]

I'm seeing delays on start; it seems related to this.  I have:

Section "InputDevice"
	Identifier      "Configured Mouse"
	Driver          "mouse"
	Option          "CorePointer"
	Option "Device" "/dev/psaux"
	Option "Protocol" "PS/2"
	Option "Emulate3Buttons" "true"
	Option "ZAxisMapping" "4 5"
EndSection

/dev/psaux has nothing attached; the system has no mouse (but for some
strange reason, X demands to have a bogus mouse configured anyway).

strace:

open("/dev/psaux", O_RDWR|O_NONBLOCK|O_EXCL) = 11
ioctl(11, SNDCTL_TMR_TIMEBASE or TCGETS, 0xbffffb9c) = -1 ENOTTY (Inappropriate ioctl for device)
ioctl(11, SNDCTL_TMR_TIMEBASE or TCGETS, 0xbffffb2c) = -1 ENOTTY (Inappropriate ioctl for device)
ioctl(11, TCFLSH, 0)                    = -1 ENOTTY (Inappropriate ioctl for device)
select(1024, [11], NULL, NULL, {0, 0})  = 0 (Timeout)
write(11, "\377", 1)                    = 1
nanosleep({0, 10000000}, NULL)          = 0
select(1024, [11], NULL, NULL, {0, 200000}) = 0 (Timeout)
ioctl(11, TCFLSH, 0)                    = -1 ENOTTY (Inappropriate ioctl for device)
select(1024, [11], NULL, NULL, {0, 0})  = 0 (Timeout)
write(11, "\377", 1)                    = 1
nanosleep({0, 10000000}, NULL)          = 0
select(1024, [11], NULL, NULL, {0, 200000}) = 0 (Timeout)
ioctl(11, TCFLSH, 0)                    = -1 ENOTTY (Inappropriate ioctl for device)
select(1024, [11], NULL, NULL, {0, 0})  = 0 (Timeout)
write(11, "\377", 1)                    = 1
nanosleep({0, 10000000}, NULL)          = 0

This didn't happen before the major X upgrade (4.2?).

I worked around this by just pointing Device at a file that doesn't exist.
