Hi Gilles,

were you able to successfully run my T_SUSP test-case after the latest
changes? For me this code still causes fatal exceptions:

#include <stdio.h>
#include <sys/mman.h>
#include <native/task.h>

void func(void *arg)
{
    printf("you should not see this\n");
    rt_task_suspend(NULL);
}

int main(int argc, char **argv)
{
    RT_TASK task;

    mlockall(MCL_CURRENT|MCL_FUTURE);
    rt_task_create(&task, "T_SUSP-test", 0, 10, T_SUSP);
    rt_task_start(&task, func, NULL);
    printf("deleting...\n");
    rt_task_delete(&task);
    return 0;
}


This is the output of the locked up system:
