Subject: Bug 1376873 - Reduce thread stack size in platform_thread.cc; r=bwc
|
|
|
|
Summary:
|
|
The current default stack size of 1M results in intermittent OOMs on win32
|
|
builds while running web-platform tests. The value of 256k was chosen for
|
|
consistency with the default value used elsewhere in Gecko, which is defined in
|
|
nsIThreadManager.idl.
