Hello Simon,

you are right. i just checked old logs - seems that previously i just
misinterpreted them

how about text that describes GC scenario like you was wrote in this
letter? plus, description of RTS +S report format - it may be added to
this scenario, i.e. "after this major GC, the following line will be
printed to +S report: ..."

for example, i still doesn't understand why

old_live + alloc - collect != new_live

in the report below (i extracted two sequential lines):

    Alloc    Collect    Live    GC    GC     TOT     TOT  Page Flts
    bytes     bytes     bytes  user  elap    user    elap
   265016    303104    840008  0.00  0.00    0.11    0.17    0    0  (Gen:  0)
   265612    266240    904196  0.00  0.00    0.11    0.17    0    0  (Gen:  0)

and completely separate topic - +RTS -s report description also
doesn't exist
