in thread Perl suddenly pauses for key input

Perhaps you could add a sig handler to your code. Something like the sig handler here:
#! use Carp; use strict; use warnings; $SIG{INT}=\&CtrlC; sub CtrlC { $SIG{INT}=\&CtrlC; Carp::carp('Caught a CTRL/C'); }; sub mySub { for (1..10) { <STDIN>; }; }; for (1..10) { <STDIN>; }; mySub(); exit;
When it hangs again, just give it a ctrl/c and see where it carps from.

    vroom: That was quite helpful. However, in Perl 5.8.8 in Windows environment, any attempt to override SIGINT or SIGBREAK will be ignored. Furthermore, my program communicates with another interface, which is old, and must be installed on Perl 5.8.8 to work. I can't upgrade my Perl version to 5.10.0.

    Anyway, the whole program is actually running within a huge Event-1.10 loop. I've setup a test environment with Perl 5.10.0 installed to experiment with your suggestion, and was letdown when Carp merely reports that CTRL/C was caught at this line:
    Event::loop;

[stevieb]: I've finally added the ability for berrybrew to fetch the list of perls available directly from Strawberry's releases.json file. Instead of pulling from there on every single call, I've added a berrybrew fetch, so it's only updated..
[stevieb]: ...on request. There's some supporting work I need to do, as well as update the docs, but it's in the v1.12 branch if anyone wants to play with it...
[stevieb]: ...issue 62 will track what else needs to be done.
