The relationship of the processes is not clear.
How many processes are there regarding windows service?
"a cygwin process" :  A (hangs)
"a window process" :  B (starts A)
"a child process"  :  C
"a windows service":  D (starts C)
perl program       :  E

A = C and B = D = E? (two processes)
or
B = C and D = E? (three processes)
or other than that?

If you can provide simple test case, it will help much.
