Linux guest: Add a delay when falling back to strace

[drmn]

It was needed for strace to catch sample execution correctly.

Generally speaking I'd rather not have time.sleep() calls with arbitrary values. What about polling the filesize of the strace/straced file every second or so, and returning from the function once it's not zero anymore (i.e., strace has written something to it and thus is initialized)?

[drmn]

Thanks for your comment. I will try to improve it reflecting your input.

[jbremer]

Any luck @drmn? :-)

[drmn]

Apologies the delay—2nd try!

[jbremer]

Could you replace the try/catch approach with a if not os.path.exists(...): continue? Bit neater imo.

[drmn]

Thanks for your comment. Yes I agree and fixed, and noticed/fixed that previous code would loop without sleep until file generation.
