According to gdb, probe_1812_locals are 10KB big, and get multiplied by
10 for MAXNESTING, which puts the total about 100KB. That's too big.
We should teach the translator to set MAXNESTING to smaller figures for
nonrecursive probes. Similarly, probe locals should not be included
in the nesting-sensitive data (locals[]).
Plus we don't REALLY have to use the percpu alloc stuff if it's that
limited.
