the thing is even if you run any command other than adb devices using system command, I am seeing the same memory increase. for example: replacing 
    system("adb devices");

the output looks like this: 
########## memory usage of perl start of execution ###########

########## memory usage of perl end of  execution ###########
perl.exe     17304 RDP-Tcp#0   1     68,372 K

My question was how can we release the memory allocated by the system command? I understand that perl doesn't release the memory back to OS but it should re-use the memory rather than allocating new memory block for each call, isn't that right?
