Request to backport 7042040: Remove disk space sanity check

[Omair Majid]

Hi,

I would like to backport the following changeset from OpenJDK7 to OpenJDK6:
7042040: Remove disk space sanity check
Summary: Remove outdated disk space checks using df
Reviewed-by: ohair, omajid
http://hg.openjdk.java.net/jdk7/build/jdk/rev/8e9e28663c5d

Unfortunately, a simple hg export/import does not work; there was some 
churn in those files. I have prepared a webrev to backport it:
http://cr.openjdk.java.net/~omajid/webrevs/sync/01/

May I commit the patch to OpenJDK6?

Thanks,
Omair
