Is it safe to compile multiple ports at the same time ?

[Paul Koch]

Hi,

Is it safe to compile multiple ports at the same time and not get the 
makes to run into each other when building dependency ports ?

I have previously got myself into a bit of a mess by starting two or 
three port builds at the same time, but haven't tried if for quite a 
while.  It would be nice to keep those other cores busy in SMP 
machines, especially when compiling things like kde and openoffice.
