commit 9b59029875a7e4d362834fe2d6017b74a044b2e6
Author: David Smith <dsmith@redhat.com>
Date:   Thu May 28 10:58:17 2009 -0500

    Avoid 1 case of holding a semaphore while mmap callbacks are being made.
    * runtime/task_finder.c (__stp_call_mmap_callbacks_with_addr): Renamed
      from __stp_call_mmap_callbacks_with_vma().  Also added some code from
      __stp_utrace_task_finder_target_syscall_exit() that locks the 'mmap_sem'
      semaphore.  This avoids holding the semaphore while the mmap callbacks
      are made.
      (__stp_utrace_task_finder_target_syscall_exit): Just calls
      __stp_call_mmap_callbacks_with_addr() in the mmap case.
