What is the meaning of the 200 __clone lines in backtraces?

Hi all, this is something I have been curious for a long time. When an
application crashes it is very common to see that the
backtraces at some point start showing:

  42 0xf750962e __clone+0x5d() in libc.so.6 (0x00000000)
  43 0xf750962e __clone+0x5d() in libc.so.6 (0x00000000)
  44 0xf750962e __clone+0x5d() in libc.so.6 (0x00000000)
  45 0xf750962e __clone+0x5d() in libc.so.6 (0x00000000)

Up to 200. Is this a bug or it is just not possible to identify when
the backtrace ends and 200 is a hard limit or what else could it be?

Best wishes,
