Drawing a sine curve in memory view of Task Manager

[Ofnuts]

Another solution:

Create many subprocesses:

• All subprocesses will try to grab a visible chunk of memory (say 50M).
  
• You start the processes at regular intervals, and each process exits after some delay, that is specific to it, with processes started first having longer lifespans.
  
• So the first process grabs memory for 20 seconds, the seconds starts one second later but has a lifespan of 18 secs, and the third has a life span of 16 seconds, etc.
  
• Once you detect the end of the first process, do it again.
  

This should create a (stepped) triangular wave. By adjusting the delays and the life spans, you can approximate your curve.
