aribiter: "broken" master

[Tom Jones <tjones@sebringring.com>]

Hello,

PCI spec R2.2, pg. 71, last paragraph, claims that if a master gets a GNT#
and does not use it within 16 clocks the arbiter may consider it "broken"
and ignore the master's REQ#.  

If a master gets GNT# and then "changes it's mind" (well within 16 clocks),
drops the REQ# and never asserts FRAME# are there any arbiters that might
consider that master "broken?"  Also, if a master does exceed 16 clocks is
it considered broken for good?  Or just until it releases it's REQ#?

Are there any known devices whose master exhibits this behavior?

Thanks in advance,
