Description:
------------
It seems that the post_max_size variable has a maximum of 
2047M -- setting it to 2048M or larger causes many bad things 
to happen, in particular it clobbers all of my POST data. I 
assume this is because if you are storing 2048M as an unsigned 
int and then treating it as an signed int later, the code is 
comparing the POST data size with a negative number. I felt so 
much pain and confusion before I found this! This should be 
documented and should probably cause an error of some kind. 
It's too late for you to save me -- please, save the others!
