Freeze in perl script after cygwin upgrade 1.5.17 -> 1.5.18

[Jacek Piskozub]

Hi,

More random ramblings:

I tried to debug the script using the ancient "print" inserting 
technique. The result was interesting. I can stop the crash from 
happening by adding a lot of print commands. Does it show it is a timing 
(race) problem?

To make it even more interesting, by adding just one (meaning instead of 
the many) print command close to the "system" one I suspect is the 
culprit, I can reproduce the alledged hang! In fact it is not a hang but 
a delayed crash. I left the script hanging and after returning to my 
office found it crashed.

Because it crashed in a novel way, I reproduce the output:

> make[1]: Entering directory `/cygdrive/d/mozilla_source/mozilla/netwerk/resources'
> +++ making chrome /cygdrive/d/mozilla_source/mozilla/netwerk/resources  => ../..
> /dist/bin/chrome/comm.jar
> +++ updating chrome ../../dist/bin/chrome/installed-chrome.txt
> /cygdrive/d/mozilla_source/mozilla/config/make-jars.pl: Could not get lockfile /
> cygdrive/d/mozilla_source/mozilla/dist/bin/chrome/installed-chrome.txt.lck.
> Remove /cygdrive/d/mozilla_source/mozilla/dist/bin/chrome/installed-chrome.txt.l
> ck to clear up
> make[1]: *** [libs] Error 255
> make[1]: Leaving directory `/cygdrive/d/mozilla_source/mozilla/netwerk/resources'


Please take note of the "Could not get lockfile" part.

Cheerio,

Jacek
