Issue with LPC2378 IRQ interrupts

Hi there,
I have 2 IRQ related ISR's in the program shown below.
ISR's 1 and 2 do the task of making an LED (connected to P2.0 and P2.7) on and off.
Iam seeing that when ISR1 is in execution(which is invoked by pressing a switch connected to P2.10 meant as external interrupt 0) and if ISR2 is invoked(which is invoked by pressing a switch connected to P2.11 meant as external interrupt 1) during that time, after completion of ISR1, the control branches to ISR2. Could anyone please suggest a method to prevent this.

#include <LPC23xx.H>

void wait(void){
  unsigned int i,j;

  for(i=0;i<=100;i++)
           for(j=0;j<=60000;j++);
}

/* External ISR 1  */
__irq void eint0_handler (void) {

  FIO2PIN = 0x00000001;
  wait();
  FIO2PIN = 0x00000000;
  EXTINT  = 0x00000001;
  VICVectAddr = 0;
}

/* External ISR 2 */
__irq void eint1_handler (void)  {

  FIO2PIN = 0x00000080;
  wait();
  FIO2PIN = 0x00000000;
  EXTINT  = 0x00000002;
  VICVectAddr = 0;
}

/* Initialize External Interrupts EINT 0/1 */
void init_eint (void) {
        EXTMODE      = 0x00000003;                           // Edge sensitive mode
        EXTPOLAR     = 0x00000000;                           // Active low, Falling edge

        VICIntSelect = 0x00000000;

        VICVectAddr14 = (unsigned long) eint0_handler;
        VICVectAddr15 = (unsigned long) eint1_handler;

        VICVectPriority14 = 0;
        VICVectPriority15 = 1;

        VICIntEnable = 0x0000C000;
}


int main (void) {

  PINSEL4 = 0x00500000;
  FIO2DIR = 0x000000FF;
  FIO2PIN = 0x00000000;

  init_eint();                                                            // Enable EINT0/1

   while (1){
           ;
   }
}
