3021 option for time-ordered output from dtrace(1M)
3022 DTrace: keys should not affect the sort order when sorting by value
3023 it should be possible to dereference dynamic variables
3024 D integer narrowing needs some work
3025 register leak in D code generation
3026 libdtrace should set LD_NOLAZYLOAD=1 to help the pid provider

/*
* This test excercises the "remnant" handling of the temporal option.
* At the end of one pass of retrieving and printing data from all CPUs,
* some unprocessed data will remain, because its timestamp is after the
* time covered by all CPUs' buffers. This unprocessed data is
* rearranged in a more space-efficient manner. If this is done
* incorrectly, an alignment error may occur. To test this, we use a
* high-frequency probe so that data will be recorded in subsequent
* CPU's buffers after the first CPU's buffer is obtained. The
* combination of data traced here (a 8-byte value and a 4-byte value)
* is effective to cause alignment problems with an incorrect
* implementation.
*
* This test needs to be run on a multi-CPU system to be effective.
