Subject: [mini] Provide a free function to the saved signal handler hash table.
X-Git-Url: http://wien.tomnetworks.com/gitweb/?p=mono.git;a=commitdiff_plain;h=14bb051f363ff2770a4ccf183b616d7cef3ddb4c

[mini] Provide a free function to the saved signal handler hash table.

This makes the cleanup code simpler, and also makes it easier to
replace saved signal handlers without having to worry about
leaking memory.
