Comment(by strake):
I can realize this on Linux 2.6.38, with GHC 7.0.3; however, the number of
ticks is not just low, but zero.
{{{$ ./program +RTS -P -RTS}}}
program.prof, in part:
{{{
total time = 0.00 secs (0 ticks @ 20 ms)
total alloc = 10,600 bytes (excludes profiling overheads)
}}}
The problem vanishes when compiled threaded, and the number of ticks is
reasonable.
