Vladimir Mezentsev 99c3fe52d2 gprofng: fix infinite recursion on calloc with multi-threaded applications
libcollector uses pthread_getspecific() and pthread_setspecific() to access
thread local memory. libcollector uses this memory to check that
interposed functions (like malloc, calloc or free) don't have recursion.
The first time we call calloc(), we call pthread_setspecific() to create
a thread-specific value.
On Ubuntu machine, pthread_setspecific() calls calloc(), and we cannot intercept
such recursion.
gcc supports thread-local storage. For example,
  static __thread int reentrance = 0;
I rewrote code using this instead of pthread_setspecific().
