Attention: Gerrit Jenkins build queue got purged

Due to some runaway builds, the Gerrit Jenkins build queue had become 
rather lengthy, it would only be processed at a slow rate, and there was 
the fear that newly submitted Gerrit patch sets could clog it again.

Therefore, we just decided on #libreoffice-dev to purge all "Gerrit 
Build v2" items from the Build Queue at <https://ci.libreoffice.org/>.

The problematic commit was reportedly 
<https://cgit.freedesktop.org/libreoffice/core/commit/?id=7e8c38b69742ff037a5e239bf0f02665f053ea53> 
"ofz#2538 avoid oom" (2017-09-19 12:50:17, GMT), which should be fixed 
with 
<https://cgit.freedesktop.org/libreoffice/core/commit/?id=ec100b7066d5a00178deb3a1625da07fd1c3b416> 
"sc: fix infinite loop in XclImpDffConverter::ProcessShGrContainer()" 
(2017-09-19 20:18:44, GMT).  Please try to avoid pushing new patch sets 
to Gerrit based on master between those two commits.

If one of your Gerrit patch sets was affected by the purge, it should 
have received a "No Builds Executed" comment from Jenkins now.  You can 
manually re-submit it by doing a rebase.
