convert/subversion: work around memory leak in svn's python bindings
The svn.ra.get_log wrapper attaches the hash of changed paths for every
log entry to a global memory pool, so memory consumption increases
rapidly, with no way to free it.
Our workaround is to call this function in a child process, and feed
its results back over a pipe. The memory consumption of the child still
grows huge (hundreds of megabytes), but at least it goes away once the
reading-the-log phase is done.

# An example CGI script to use hgweb, edit as necessary
# send python tracebacks to the browser if an error occurs:
import cgitb
cgitb.enable()
# adjust python path if not a system-wide install:
#import sys
#sys.path.insert(0, "/path/to/python/lib")
# If you'd like to serve pages with UTF-8 instead of your default
# locale charset, you can do so by uncommenting the following lines.
# Note that this will cause your .hgrc files to be interpreted in
# UTF-8 and all your repo files to be displayed using UTF-8.

#import os
#os.environ["HGENCODING"] = "UTF-8"
