also each line in here could be prefixed with 'code action'
that led to the result on the line, like:
* exec: result:
*
* __test_function - fd1 event breakpoint hit -> count1 == 1
* - SIGIO is delivered -> overflows == 1
* sig_handler - fd2 event breakpoint hit -> count2 == 1
* - SIGUSR1 is delivered -> overflows_2 == 1 (nested signal)
* - sig_handler_2 return
* - sig_handler return
* incq (%rdi) - fd3 event watchpoint hit -> count3 == 1 (wp and bp in one insn)
* - SIGIO is delivered -> overflows == 2
hum.. but it might take all the fun out of it ;-)
