There's no excuse to have code in synthetic filestores that allows direct
references to the textvp anymore.

is enough to satisfy things like StarOffice. This is a hack, but doing
it properly would be a LOT of work, and would require extensive grovelling
around in the user address space to find the argv[].

nodes; this also apparantly caused a panic in some circumstances.
Also, since procfs_exit() is getting rid of the nodes when a process
exits, don't bother checking for the process' existance in procfs_inactive().
what is teh root cause -- but, sometimes, a procfs vnode in pfshead is
apparantly corrupt (or a UFS vnode instead). Without this patch, I can
get it to panic by doing (in csh)
while (1)
ps auxwww

and it will panic when the PID's wrap. With it, it does not panic.
Yes -- I know that this is NOT the right way to fix it. But I haven't
been able to get it to panic yet (which confuses me). I am going to
be looking into the vgone() code now, as that may be a part of it.
Note that an unload facility should be used to call rm_at_exit() (if
procfs is being loaded as an LKM and is subsequently removed), but it
was non-obvious how to do this in the VFS framework.

in procfs_allocvp(). This fixes at least stat() of /proc/*/mem.
stat() of /proc/*/file already worked. I think procfs_allocvp() isn't
actually called for type Pfile.

without the appropriate Lite/2 userland changes.
The system boots and can mount UFS filesystems.
Untested: ext2fs, msdosfs, NFS
Known problems: Incorrect Berkeley ID strings in some files.
Mount_std mounts will not work until the getfsent
library routine is changed.

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
to information from a single process causes hangs. Specifically, this
fixes problems (hangs) with concurrent ps commands, when the system is under
heavy memory load.

process won't possibly block before filling in the fsnode pointer (v_data)
which might be dereferenced during a sync since the vnode is put on the
mnt_vnodelist by getnewvnode.
