Zdenek Kabelac	e585a6bbcf	signals: better nesting support ... Support upto 3 levels os nesting signal blocking. As of today - code blocks signals immediatelly when it opens VG in read-write mode - this however makes current prompt usage then partially unusable since user may not 'break' command during prompt (something most user would expect). Until a better fix for prompting is implemented, put in support for signal nesting - thus when prompt enables signal acceptance, make it possible to really break command at this point.	2014-05-07 14:09:33 +02:00
Zdenek Kabelac	31ac200a37	debug: add more debug message for signal handling ... Adding log_sys_debug for eventual logging of system errors. (Using debug level, since currently signal handling functions do not fail when any error is encoutered).	2014-05-07 14:07:13 +02:00
