IDL is innocent here. The allocation is done by the underlying operating
system. I guess you are on windows :-)

On my linux box, with 1 GByte memory:

IDL> a1=bytarr(1000,1000,500)
IDL> a2=bytarr(1000,1000,500)
IDL> help, /mem
heap memory used: 1000577500, max: 1000577516, gets: 423, frees: 115

You can read about memory allocation on windows here:
