[issue577] memory error, even if half of the memory is free, and additional paging file is there

[THURNER rupert]

New submission from THURNER rupert <rupert.thurner at gmail.com>:

on a intel pc with 2 gb of memory, 800 mb committed to programs, 1.2gb free, 
we tried to add a 270mb binary file to a newly created repository. memory 
commit rises up to 1.1 gb or so, and then:

c:\temp> hg init
c:\temp> hg add big-file
c:\temp> hg commit
** unknown exception encountered, details follow
** report bug details to http://www.selenic.com/mercurial/bts
** or mercurial at selenic.com

subsequent tries fail immediately, without using memory.
