OK, I cloned a new repository and started applying patches to it. The
transcript of what I did is attached. You can see that after I
disconnect from the network, I get three emails imported before it spits
an error at me.

Description: Use msleep() instead of schedule_timeout()
to guarantee the task delays as expected. Originally
submitted to linux-scsi by the janitors, and resubmitted
by boutcher (after testing :-)

Description: Limit the size of I/O requests sent by the
ibmvscsi adapter. With better I/O scheduling (and thus larger
requests) we were breaking some servers.

bk commit -y[PATCH] gdth: reduce large on-stack locals

gdth is the fourth-highest stack user (for a single function)
in 2.6.10-rc3-bk-recent (sizes on x86-32).

Reduce stack usage in gdth driver:
reduce ioc_rescan() from 1564 to 52 bytes;
reduce ioc_hdrlist() from 1528 to 24 bytes;
reduce gdth_get_info() from 1076 to 300 bytes;

[HERE BK POPS UP A DIALOGUE SAYING:

Unable to obtain permission to use this version of BitKeeper (bk-3.2.3)
from lease.openlogging.org. That server issues certificates to use BK
for openlogging for 30 days at a time. The bk binary needs to be able
to make a http connection to lease.openlogging.org at least once a month.

Look at 'bk help url' if you need to tell 'bk' about a proxy.

AND THE COMMIT FAILS WITH THE FOLLOWING:]

You need to figure out why you have two files with the same ID
and correct that situation before this ChangeSet can be created.
