Output formats suppressed after first write

[ykempf]

I have observed this several times on various platforms, today on HazelHen.

1. I set export PHIPROF_PRINTS=full,detailed in the job script.
2. At the first phiprof output I get both sets of data.
3. Subsequent writeouts only include full, detailed is absent.

Last time I had/noticed this problem, it was with groups,compact,full I think and after the first writing I only got groups (but I'm not 100% sure anymore, it may be documented in Flowdock).
