Fixed threadpool hang and added lots of smoketests.
* Fixed bug in threadpool logic when calling CleanupAnyWorkersSharingAllocator - this was deleting the worker's thread death notifier in the context of a worker thread (which is only allowed from the context of the main thread).
* Added lots more smoketests
* Added --overwrite option to fzip (previously unzipping would always overwrite)
To update the icon files:
1) Edit the .sgv file useing an editor such as Inkscape. Note, things like text
must be converted using "Path | Object to path" if they are to survive the next
step.
2) Convert the .sgv file to a Tiny SGV file using Nokia's SGV2SGVT tool (available in
the S60 SDK).
3) Convert the Tiny SGV file to a .mif file using "mifconv" as follows:
\epoc32\tools\mifconv fshell_local.mif /x /c32 fshell_local.tiny.svg
Note, it is important that the .mif file is not encoded in binary XML (the "/x"
option arranges for this) because not all S60 handsets can handle the more compact
format.
