Use pthread_mutex_lock/unlock().  You need to declare a global mutex:

#include <pthread.h>

static pthread_mutex_t mutex = PTHREAD_MUTEX_INITIALIZER;

Then make sure only one thread is in your overriden functions at a time.

my_malloc(...)
{

  pthread_mutex_lock (&mutex);

  install old hooks...
  malloc...
  install my hooks again...

  pthread_mutex_unlock (&mutex);

  return...
}


Hope that helps.
