I have not managed to get output from a strace call like the one above.

FWIW:

A snippet of strace output from an earlier posting of mine.

This is PART of the output of scripting *similar* to:

 $ cat etc/postinstall/t2.sh
 #!/bin/sh
 strace -o /t3.strace bash -c /t3.sh

 $ cat /t3.sh
 BLAH=$(cygpath -A -P)

This means:

$ find -type f | xargs grep -n 'spawned windows pid'
./spawn.cc:834:  sigproc_printf ("spawned windows pid %d", pi.dwProcessId);

...that is one of the last things that happens before the hang.
i.e. just telling the same that you already know.

It is here the cygpath "hang" is active...
It continues below after a "kill -9 ..."
