If /usr/sbin/sysinstall is linked to another filename, say
`/usr/local/bin/configPackages', then the basename will be used
as an implicit command name.
To get a list of modules you can link to, see `bsdconfig -h' output.

typically bound to Shift-Tab. syscons produces ^]]Z for Shift-Tab, like
many VT100-like terminal (emulators). The plain xterm does not produce
this sequence, but ^I for both Tab and Shift-Tab.

here is race between decaying the resource usage in containers, and updating
per-process usage; basically, the former may cause per-container usage
to get smaller than per-process usage.

This was broken by me when merging the 802.11n aggregate descriptor chain
setup with the default descriptor chain setup, in preparation for supporting
AR9380 NICs.
The corner case here is quite specific - if you queue an aggregate frame
with >1 frames in it, and the last subframe has only one descriptor making
it up, then that descriptor won't have the rate control information
copied into it. Look at what happens inside ar5416FillTxDesc() if
both firstSeg and lastSeg are set to 1.
Then when ar5416ProcTxDesc() goes to fill out ts_rate based on the
transmit index, it looks at the rate control fields in that descriptor
and dutifully sets it to be 0.
It doesn't happen for non-aggregate frames - if they have one descriptor,
the first descriptor already has rate control info.
I removed the call to ath_hal_setuplasttxdesc() when I migrated the
code to use the "new" style aggregate chain routines from the HAL.
But I missed this particular corner case.
This is a bit inefficient with MIPS boards as it involves a few redundant
writes into non-cachable memory. I'll chase that up when it matters.
Tested:
* AR9280 STA mode, TCP iperf traffic
* Rui Paulo <rpaulo@> first reported this and has verified it on
his AR9160 based AP.

- Implement a function to ensure that all preempted threads have switched
back out at least once. Use this to make sure there are no stale
references to the old ktr_buf or the lock profiling buffers before
updating them.

sleep, and perform the page allocations with VM_ALLOC_SYSTEM
class. Previously, the allocation was also allowed to completely drain
the reserve of the free pages, being translated to VM_ALLOC_INTERRUPT
request class for vm_page_alloc() and similar functions.
Allow the caller of malloc* to request the 'deep drain' semantic by
providing M_USE_RESERVE flag, now translated to VM_ALLOC_INTERRUPT
class. Previously, it resulted in less aggressive VM_ALLOC_SYSTEM
allocation class.
Centralize the translation of the M_* malloc(9) flags in the single
inline function malloc2vm_flags().
