Level-triggered process 'Event's

[garrinkimmell]

I want to be able to generate asynchronous resets, which in VHDL would look like:

process foo(clk,rst) is
begin
if (rst = '1') then
blah
elsif rising_edge(clk) then
blah
end if;
end process;

But currently the 'Event' structure only allows for edge-triggered values. I realize 'level-triggered' and 'event' are kind of non-compatible, but I would like to see how we should do this using Netlist.
