revlog: break up compression of large deltas

Python's zlib apparently makes an internal copy of strings passed to
compress(). To avoid this, compress strings 1M at a time, then join
them at the end if the result would be smaller than the original.

For initial commits of large but compressible files, this cuts peak
memory usage nearly in half.

a subset of the headers plus the body of the result."""

import httplib, sys
headers = [h.lower() for h in sys.argv[3:]]
conn = httplib.HTTPConnection(sys.argv[1])
conn.request("GET", sys.argv[2])
response = conn.getresponse()
print response.status, response.reason
for h in headers:
    if response.getheader(h, None) is not None:
        print "%s: %s" % (h, response.getheader(h))
print
sys.stdout.write(response.read())
