We already have flight recorder on memory. However, sometimes user needs on-file
flight recorder mode for system auditing and system performance logging
(Perhaps, someday someone might want flight recorder over network too, but that
is another story :) ).
This flight-recorder on memory feature requires
- setting maximum file size (and wrap-around writing which is able to overwrite
trace data when file size reaches maximum)
- signal-handler for log-file switching without any information loss (like as
logrotate) for auditing use.

Oops, this one should be
-switching to new log-file when exceeding specified file size without any loss.

This feature could be change -F option, or the combination of options.
For example:
Idea A) modifying -F option
$ stap -F memory xxx.stp -> flight recorder on memory
$ stap -F file=1G -o file xxx.stp -> flight recorder on file(When the file size
reaches 1GB, change to next file (file.1->file.2->file.3->...))
$ stap -F file=1G,2 -o file xxx.stp -> flight recorder on file(When the file
size reaches 1GB, change to next file. And rotate 2 files for
recording(file.1->file.2->file.1->...))
B) or combination of options
$ stap -F xxx.stp -> flight recorder on memory
$ stap -F -o file -S 1G xxx.stp -> flight recorder on file(When the file size
reaches 1GB, change to next file (file1->file2->file3->...))
$ stap -F -o file -S 1G,2 xxx.stp -> flight recorder on file(When the file size
reaches 1GB, change to next file. And rotate 2 files for
recording(file1->file2->file1->...))
