[issue1863] hg clone out of memory errors

[daveb]

New submission from daveb <david.beard at oa.mo.gov>:

We are having a problem with a repository and I have seen others reporting 
similar issues. What we see is the following on an hg clone done from the 
command line:

requesting all changes
adding changesets
adding manifests
adding file changes
transaction abort!
rollback completed
Traceback (most recent call last):
  File "mercurial\dispatch.pyc", line 43, in _runcatch

MemoryError
abort: out of memory

The version is:

Mercurial Distributed SCM (version 1.3.1)

TortoiseHG will just show the error for the transaction abort and no other 
messages. 

Is there any way to adjust the memory usage? Or is this a code bug?
