'put URL' fails if previous 'put URL' call hasn't finished

[Andre Garzia]

Trevor,

I did a silly as hell semaphore function called SafePut which is just a 
wrapper for put but it checks for a global prior to putting, if the 
global is set then it waits and loop, when the global is unset, it does 
the put url and sets the global. Don't know what happens if the put 
URLs are issued at the same time, I think one should implement a Queue 
data type and goes poping the puts when it's safe... or rev team could 
do that...

Cheers
andre
