Hi, sorry, just delete a couple lines of code, was trying to get mail
shorter, here's the complete code

#include <unistd.h>
#import <Foundation/Foundation.h>
@interface MyObj:NSObject
@end

@implementation MyObj
- (void) launch
{
      // id p = [NSAutoreleasePool new];
       NSLog(@"x");
       //[p release];
}
@end

int main (int argc, const char * argv[]) {
       id p = [NSAutoreleasePool new];

       id obj = [MyObj new];
       [NSThread detachNewThreadSelector:@selector(launch)
toTarget:obj withObject:nil];
       [NSThread detachNewThreadSelector:@selector(launch)
toTarget:obj withObject:nil];

sleep(20);
return 0;
}
