config.xml. Use the boolean tag <cache_md5_info> to enable it.
This prevents the work generation library from having to go back and
continuously regenerate the md5 sums of your input data files. Note
that reading these from disk can be expensive if you have many such files
that are large and that you re-use. See check-in notes from 30/31 Dec 2004
for some details.

no work was sent to hosts, and available space<0 OR if available space>0
but work was unfeasible because the disk bound requirements of the work
exceeded the available space.
Added a new config.xml boolean element called 'choose_download_url_by_timezone'
This requires that projects provide a 2-column file in the project root named
'download_servers'. An example is:
3600 http://einstein.aei.mpg.de
-21600 http://einstein.phys.uwm.edu
The first column is offset from UTC in seconds, and the second column is the URL
of the download server. When enabled, the scheduler will replace the download
path for data and executables by a list of download URLs, ordered by proximity
to the host's timezone. The download path must start with the
BOINC default download/ and the different download servers must have identical
file paths under download/, in other words they must be mirrored.

< 4.62 to be interchanged with their priority. So if the message was
supposed to be 'No work available' with priority 'low', the actual

disk space is < 0, delete files which have <sticky> and <report_on_rpc>
set. Note that (1) this deletion simply removes the <sticky> tag, so
file won't be deleted until after all WU that depend upon it are
completed and (2) the mechanism to determine which file to delete
could be improved. TODO: improve messages to hosts which have no file
space and ALSO have no files to delete.
- scheduler changes: locality scheduling. Clean up code which makes a
deterministic search of results to delete. Data files names can not
contain the "~" character!
- scheduler changes: added a simple debugging mechanism for scheduler
replies. If you touch a file named 'debug_sched' in the project
root, then files called sched_reply_HOSTID_RPCNO will be created
under cgi-bin/ which contain the scheduler replies. You can turn on
this mechanism for some time to study the scheduler replies.
In a little while I will add a similar debugging feature which also
prints the corresponding scheduler requests.
