The problem with Safari is that it may use any closed keepalive 
connection to send POST and this will result in problems.  That 
is, the only way to mitigate the problem is to completely disable 
keepalive connections with Safari.

Probably acceptable solution would be to change keepalive_disable 
default to "msie6" (which would disable keepalives with old MSIE 
after POSTs) leaving "safari" as a workaround option for people 
who really use POSTs and see problems with Safari.
