Hi Jambo Hamon,

Regarding Mutex (standalone module) and MCE::Mutex, multiple calls to mutex lock or enter by the same process or thread are safe from within dynamically nested scopes. The behavior is similar to locking using threads and threads::shared.

The hash may be shared. Below is the diff output.

$ diff orig.pl script.pl
33a34
> use MCE::Shared;
51c52
< my %t;
---
> tie my %t, 'MCE::Shared';
217c218
<     print Dumper( \%t );
---
>     print Dumper( tied(%t)->export( { unbless => 1 } ) );

The shared hash resides under the shared-manager process. Deep-sharing a non-blessed structure recursively is handled automatically via the TIE-shared interface. To see the key-value pairs, call the export method. The unbless option unblesses any shared array, hash, and scalar object to a non-blessed array, hash, and scalar respectively.

Regards, Mario
