45afe06953 I now understand why name caching was redone for 4.4BSD; Net/2's 
method of caching names has a totally bogus interface.  kill *ALL*
caching of names when going through a lofs, because that's the only
way to make sure things always work right.  Also, XXX the possibly-bogus
check i keep whining about.  it's almost certainly wrong, but it's
too weird to modify significantly; even jsp didn't want to touch it...

b02974b037 Jay Fenlason <hack@datacube.com>: 
1: the fi_readers and fi_writers fields of the fifoinfo structure were not
being initialized to 0.  This caused the driver to not sleep the first
process to open the fifo--it thought there was already another process to
talk to (most of the time.)

2: fifo_open() was calling tsleep() without unlocking the inode of the fifo
file.  This caused *any* subsequent access to the file (even an ls (!)) to
hang forever.  Note that this bug was usually masked by bug #1 above.
