Denial of service in microkernel

[Gayathri Nagarajan]

I executed fork bomb(a process continually replicates itself to deplete the
system resources), a denial of service attack in Linux kernel and the
kernel got crashed. This is because of the depletion of resources and
starvation.

But, upon executing the same application in L4linux under the Fiasco.oc
with L4re microkernel architecture, no crashing occurs.
What is the reason behind this stability? How does the
microkernel(Fiasco.OC) handle the system calls ?

# Code for the fork bomb application :

#include<unistd.h>
int main(void)
{
while(1)
fork();  //system call
}
