  70 Can anyone in-the-know shed some light on how notmuch generates its\r
  71 thread ids? Until recently, I'd only seen numeric thread ids 16\r
  72 characters long, padded with zeroes. For example:\r
  73 \r
  74 thread:0000000000000001\r
  75 thread:0000000000000002\r
  76 thread:0000000000000005\r
  77 etc etc\r
  78 \r
  79 Today, several new threads were created with non numeric ids:\r
  80 \r
  81 thread:000000000000000d\r
  82 thread:000000000000000e\r
  83 thread:000000000000000f\r
  84 \r
  85 Is this normal behavior?\r
