[TK Soh]

New submission from TK Soh <teekaysoh at gmail.com>:

just receive a traceback with the latest crew version. Apparently the
workstation ran out of memory:

% hg clone --pull -U source
requesting all changes
adding changesets
adding manifests
adding file changes
** unknown exception encountered, details follow
** report bug details to http://www.selenic.com/mercurial/bts
** or mercurial at selenic.com
** Mercurial Distributed SCM (version dfe87137ed14)
